Should that be ...

export CFLAGS="-xcode=pic32"
export CXXFLAGS="-xcode=pic32"

... neither of those methods will remove/replace the -KPIC flag from
the compile line.  But yeah, that brings up another issue; I don't
want to unnecessarily compile all of my code with -xcode=pic32 when it
doesn't need to.

TIA,
George.
