description:
Obtain the MKPIE flags from the environment

This solves an issue with the command sink component of the MKPIE
wrapper for GCC, where the contents of the _MKPIE_CFLAGS.gcc and
_MKPIE_LDFLAGS.gcc variables was guessed. It is now communicated to
cmd-sink-mkpie-gcc through the environment instead.
