gcc4 "response file" handling broken.

This is hrev46383.

Trying to link WebKit shared libraries (these have a lot of files). A response file is used to avoid hittng the command line limit.

But gcc unfolds the command-line before passing it to collect2.

FAILED: : && /bin/distcc g++-x86 -fPIC -march=pentium4 -msse2 -mfpmath=sse -std=gnu++0x -O3 -DNDEBUG -Wl,--no-undefined -shared -Wl,-soname,libWebCore.so.1 -o lib/x86/libWebCore.so.1.2.0 @CMakeFiles/WebCore.rsp && : [17:56] <PulkoMandy> g++-x86: error trying to exec '/boot/system/develop/tools/x86/bin/../lib/gcc/i586-pc-haiku/4.7.3/collect2': execv: Argument too big

This should work since gcc 4.5.0 but may require the --with-gnu-ld option when configuring gcc: ​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45749

Or this may be another problem, as the issue happens when running collect2, not ld.

The problem was not passing --with-gnu-ld to gcc configure script, so it didn't know the linker was able to use response files.
