I did:

setenv LIBGCC2_DEBUG_CFLAGS -gdwarf-2
setenv TARGET_LIBGCC2_CFLAGS -gdwarf-2

                setenv GPC_CONFIG_EXTRAS "--with-arch=pentium-m --with-tune=prescott --without-stabs"

Ok, I found:
http://developer.apple.com/devcenter/download.action?path=/Developer_Tools/Xcode_6.4/Xcode_6.4.dmg

This went into /Applications and so I set this inside the build script:

setenv GPC_SDK /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
setenv GPC_ALWAYS_USE_SDK       1

It crashed:

The directory that should contain system headers does not exist:
  /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs//usr/include
make[2]: *** [stmp-fixinc] Error 1
make[1]: *** [stage1_build] Error 2
make: *** [bootstrap] Error 2

This is a total mess.
