[Buildroot] [PATCH 3/5] package/openmpi: enable mpi compiler wrapper scripts

[Julien Olivain]

openmpi normally includes compiler wrapper binary programs (e.g. mpicc,
mpicxx, etc...). Those programs are inconvenient when cross compiling.
Those target binary wrappers are useless in Buildroot, as the target
root filesystem does not include compilers. For cross compilation,
openmpi also ships Perl scripts providing a subset of those functions.
With those compiler wrappers, openmpi programs can now be cross
compiled properly in Buildroot. This patch enables those wrappers.
