Log Message:
PR/55802: Andreas Gustafsson: Unbreak reproducible builds.
For reproducible builds to work we need to have a consistent command
line (because the command line gets recorded in dwarf). So we can't
do:
-ffile-prefix-map=/joe/random/src=/usr/src
because then /joe/random/src gets recorded. We do instead:
-ffile-prefix-map=\$NETBSDSRCDIR=/usr/src
The patch restores the environment variable parsing that got lost
in the last 2 gcc upgrades.
