mpich-* @3.1.4: "ccache" and "distcc" get written into wrapper scripts

[larryv (Lawrence Velázquez)]

The MPICH wrapper scripts remember the compilers used to create them.

# Default settings for compiler, flags, and libraries.
# Determined by a combination of environment variables and tests within
# configure (e.g., determining whehter -lsocket is needee)
CC="/opt/local/bin/gcc-mp-5"

If a user has enabled configureccache or configuredistcc, then that will get baked into the wrapper scripts as well.

CC="ccache /opt/local/bin/gcc-mp-5"

This is undesirable; I ran into problems accessing the ccache cache while trying to compile other ports. I’ve attached a patch that fixes this by disabling the use of ccache and distcc. (I don’t know whether all the revbumps are necessary.)
