build parsec for ARM

reference document: http://www.cs.utexas.edu/~parsec_m5/TR-09-32.pdf
cross-compilation environment:
1. HOSTTYPE=arm
2. PATH=/path/to/fake/uname/bin:$PATH
content of /path/to/fake/uname/bin/uname:
===============================
$ cat ~/research/benchmarks/parsec-2.1-arm/fake-uname/uname
#!/bin/sh

/bin/uname $* | sed 's/i686/armv7l/g'

===============================

3. cross compilation tools: arm-linux-gnueabi-*

4. host machine is i686

Steps:

1. compile tools natively

$ parsecmgmt -a build -p tools

Note: for now, use native i686 compilation flags in gcc.bldconf

2. compile apps to ARM binary:

1. set BINARY_PREFIX options in gcc.bldconf

2.1 blackscholes : OK

2.2 bodytrack:

  2.2.1 In pkgs/apps/bodytrack/src/config.h.in, comment out #undef malloc

before change:

/* Define to rpl_malloc if the replacement function should be used. */

#undef malloc

after change:

/* Define to rpl_malloc if the replacement function should be used. */

//#undef malloc

  2.2.2 In  pkgs/apps/bodytrack/parsec/gcc-pthread.bldconf, add --host and --build.

before:

# Arguments to pass to the configure script, if it exists

build_conf="--enable-threads --disable-openmp --disable-tbb"

after:

# Arguments to pass to the configure script, if it exists

build_conf="--enable-threads --disable-openmp --disable-tbb --build=i686-linux-gnu --host=arm-linux-gnueabi"

2.3: facesim: OK

2.4: ferret: depends on gsl and imagick, so build them first, see 2.5, and 2.6. OK

2.5: gsl: 

  2.5.1 In  pkgs/libs/gsl/parsec/gcc.bldconf, add --host and --build.

before:

# Arguments to pass to the configure script, if it exists

build_conf="--disable-shared"

after:

# Arguments to pass to the configure script, if it exists

build_conf="--disable-shared --build=i686-linux-gnu --host=arm-linux-gnueabi"

2.6: imagick: In  pkgs/libs/imagick/parsec/gcc.bldconf, add --host and --build.

before:

# Arguments to pass to the configure script, if it exists

build_conf="--disable-shared --without-perl --without-magick-plus-plus --without-bzlib --without-dps --without-djvu --without-fpx --without-gslib --without-jbig --with-jpeg --without-jp2 --without-tiff --without-wmf --without-zlib --without-x --without-fontconfig --without-freetype --without-lcms --without-png --without-gvc --without-openexr --without-rsvg --without-xml"

after:

# Arguments to pass to the configure script, if it exists

build_conf="--disable-shared --without-perl --without-magick-plus-plus --without-bzlib --without-dps --without-djvu --without-fpx --without-gslib --without-jbig --with-jpeg --without-jp2 --without-tiff --without-wmf --without-zlib --without-x --without-fontconfig --without-freetype --without-lcms --without-png --without-gvc --without-openexr --without-rsvg --without-xml  --build=i686-linux-gnu --host=arm-linux-gnueabi"

2.7: freqmine: OK

2.8: raytrace: SKIP. In order to compile raytrace, libX11 must be cross-compiled which requires cross-compiling the following libraries:

libX11

libXmu

libXext

libxcb

xproto

xextproto

xtrans

libpthread_stubs

libXau

kbproto

inputproto

jpeg

2.9: swaptions: OK

2.10: fluidanimate: OK

2.11: vips: depends on glib and libxml2. libxml2 and vips only need to add --build and --host.
  2.11.1: remove -L${CC_HOME}/lib in config/gcc.bldconf
before:

export LDFLAGS="$STATIC -pthread -L${CC_HOME}/lib"


after:

export LDFLAGS="$STATIC -pthread"

2.12: glib: add --host and --build in pkgs/libs/glib/parsec/gcc.bldconf.

  2.12.1
before:

# Arguments to pass to the configure script, if it exists

build_conf="--disable-shared --enable-threads --with-threads=posix"

after:

# Arguments to pass to the configure script, if it exists

build_conf="--disable-shared --enable-threads --with-threads=posix --build=i686-linux-gnu --host=arm-linux-gnueabi"
  2.12.2 In pkgs/libs/glib/src/configure, add following line at line 43:

ac_cv_func_posix_getpwuid_r=no$
glib_cv_stack_grows=no$
glib_cv_uscore=no$

2.13: dedup: OK.  depends on ssl, see 2.14
2.14: ssl: OK.
  2.14.1change gcc to arm-linux-gnueabi-gcc in pkgs/libs/ssl/src/Configure.pl line 323
