Ah, it's Arch Linux and you're right,
is in the default package build environment (the environment packages
are to be built in, not the environment users are running). I'll use
MPICH2LIB_LDFLAGS so it doesn't go into the wrapper (I already did this
for CFLAGS, but forgot LDFLAGS when upstream started setting it by
default). Sorry for the confusion, and here is the Arch package.
