After successfully building LLVM + clang, I wanted to run the tests.
The tests start out with

ulimit -t 600 ; ulimit -d 512000 ; ulimit -m 512000 ; ulimit -v 1024000 ;

I understand that there is no support for setting those limits, but
the behaviour of 'ulimit -m' seems inconsistent:

/bin/sh: line 0: ulimit: -m: invalid option
ulimit: usage: ulimit [-SHacdfilmnpqstuvx] [limit]
--------------------------------^

If -m isn't a valid option, it shouldn't appear in the usage.
