OSX awk does not support third argument to "match" function

[Chad Parker]

The OSX version of the "match" function in awk does not support the third argument. The GNU version puts what was matched into the third argument, but the OSX version stores the match data in RSTART and RLENGTH.

A solution is to install gawk from macports. autotools will then use the gawk instead of the OSX awk.

Another solution would be to use RSTART and RLENGTH instead, which are also supported by gawk.

make fails with:

/bin/sh ./m4lib_to_newlib.sh --contents \
  pcblib.contents --output pcblib-newlib \
   --pcb "../src/pcb" --awk "awk"

 context is
