Fix exec_prefix commit

[fosslinux]

67441aa broke grub. So we reverted it in 9bdf2f6. Now we need to fix it again.

17:35 <sgn[m]> I think better to revert c96738a6e9 and rebuild grub for now. I'll find the packages that requires that arguments and fix it later

17:24 <sgn[m]> GRUB_LIBDIR is defined to unexpanded exec_prefix
17:25 <sgn[m]> I think we need to overwrite the --libdir for grub
17:30 <sgn[m]> Hm, or rrplace --exec-prefix=/usr in common/environment/configure/gnu-configure-args.sh
17:30 <sgn[m]> Don't know if any side effects
17:31 <sgn[m]> Maybe changes in pkg-config files

It's openmpi being retarded, it invented its own version of AC_CONFIG_SUBDIRS.

OpenMPI is fixed.
