split skia.gyp into separate gypfile for each source dir
see http://codereview.appspot.com/4527084/
Now, to build out/Debug/SampleApp on Linux, do the following:
cd trunk/gyp
rm -rf Makefile *mk *.Makefile out
./gyp_skia -fmake --ignore-environment "--toplevel-dir=$PWD" \
-Icommon.gypi "--depth=$PWD" SampleApp.gyp
make

+ # Due to an unfortunate intersection of lameness between gcc and gyp,
+ # we have to build the *_SSE2.cpp files in a separate target. The
+ # gcc lameness is that, in order to compile SSE2 intrinsics code, it
+ # must be passed the -msse2 flag. However, with this flag, it may
+ # emit SSE2 instructions even for scalar code, such as the CPUID
+ # test used to test for the presence of SSE2. So that, and all other
+ # code must be compiled *without* -msse2. The gyp lameness is that it
+ # does not allow file-specific CFLAGS, so we must create this extra
+ # target for those files to be compiled with -msse2.
+ #
+ # This is actually only a problem on 32-bit Linux (all Intel Macs have
+ # SSE2, Linux x86_64 has SSE2 by definition, and MSC will happily emit
+ # SSE2 from instrinsics, while generating plain ol' 386 for everything
+ # else). However, to keep the .gyp file simple and avoid platform-specific
+ # build breakage, we do this on all platforms.
+
+ # For about the same reason, we need to compile the ARM opts files
+ # separately as well.
