 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.
