Cross-compiling success

I took another stab at directly cross-compiling (not via distcc) using toolwhip. My previous attempt failed, but not due to libffi at all. The problem there was that I had the Mac ld in my path before the host ld. After fixing that and a few mozilla build system issues and making sure the build system can find the right SDK and the right ar and such I now have a cross-compile setup working. No make package yet, since that requires the dmg-creation utility which I don't have on the Linux machine. No --enable-breakpad support yet due to bug 543111. --enable-shark needs headers I don't have on that machine yet, so I'd need to sort that out. But for basic bisecting, this works.

Just so I can find it later, the working mozconfig file I'm using is something along these lines:

mk_add_options MOZ_MAKE_FLAGS="-s -j10"
export MOZ_MAKE_FLAGS="-s -j10"

mk_add_options CC="ccache /Developer/usr/bin/gcc-4.2"
export CC="ccache /Developer/usr/bin/gcc-4.2"

mk_add_options CXX="ccache /Developer/usr/bin/g++-4.2"
export CXX="ccache /Developer/usr/bin/g++-4.2"

mk_add_options CROSS_LIB_PATH="/Developer/usr/lib:/Developer/SDKs/MacOSX10.5.sdk/usr/lib"
export CROSS_LIB_PATH="/Developer/usr/lib:/Developer/SDKs/MacOSX10.5.sdk/usr/lib"

mk_add_options CROSS_COMPILE="1"
export CROSS_COMPILE="1"

export LD=/Developer/usr/bin/ld
export AR=/Developer/usr/bin/ar

mk_add_options PATH="/home/bzbarsky/bin:/usr/lib64/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/lib64/ccache:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/Developer/usr/bin:/Developer/SDKs/MacOSX10.5.sdk/usr/bin"

ac_add_options --target=i686-apple-darwin9
ac_add_options --enable-application=browser
ac_add_options --with-macos-sdk=/Developer/SDKs/MacOSX10.5.sdk
ac_add_options --disable-crashreporter
ac_add_options --disable-optimize
ac_add_options --enable-debug
ac_add_options --disable-tests

Various other --enable-whatever are hanging out in there too, but the above are sort of the minimal set one needs at the moment.
