[Buildroot] [PATCH] valgrind: do not use host mpicc

[Jérôme Pouiller]

Valgrind may use 'mpicc' (from openmi project) to compile libmpiwrap-*.so.
Without any option, it will detect and use 'mpicc' from host and generate
libmpiwrap-*.so for host:

  $ file target/usr/lib/valgrind/libmpiwrap-arm-linux.so
  target/usr/lib/valgrind/libmpiwrap-arm-linux.so: ELF 64-bit LSB  shared object,
  x86-64, version 1 (SYSV), dynamically linked, not stripped

We simply disable openmi support for valgrind.

Not sure why you're adding another CONF_OPTS assignment instead of
re-using the existing one, so I've refactored that a bit and applied.

Thanks!
