You might get better luck with crosstool-ng running on the shell by itself with newer binaries for m4 and such earlier on the path. Alternatively, see if you can edit bootstrap to pre-qualify m4 to disregard those that don't accept --gnu > Try `/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/m4 --help' for more information. > autom4te: /usr/bin/m4 failed with exit status: 1 > Gandalf:crosstool-ng pteeson$ > Gandalf:crosstool-ng pteeson$ m4 --version > GNU M4 1.4.6 Yes, but which m4 ?
