arm-none-eabi-gcc @5.1.0_1 does not build on OS X Lion using clang

[daniel@…]

On OS X Lion (10.7.5, Darwin 11.4.2), the default compiler (Clang as Apple LLVM version 4.2 (clang-425.0.28)) bails out with an error during build:

:info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_cross_arm-none-eabi-gcc/arm-none-eabi-gcc/work/gcc-5.1.0/gcc/config/arm/neon.md:3463:10917: fatal error: parser recursion limit reached, program too complex

Solution is to blacklist all clang versions in the Portfile by being more inclusive:

compiler.blacklist {clang < 500}

This forces the compiler chosen to be Xcode LLVM-GCC 4.2, which results in a succesful build, although it complains during staging:

I'm cleaning up some tickets and I'm somewhat confused by this one. According to ​http://packages.macports.org/arm-none-eabi-gcc/ the port currently builds on Lion. Some other crossgcc compilers seem to be blacklisting {clang >= 421 < 422} (apparently there used to be a problem at some point which was fixed later; most ports don't blacklist those because users are no longer supposed to have an old Xcode installed), but your report is about clang 425.

I'm closing it as I believe it has been fixed. If not, please reopen.
