first stab at -ffunction-sections

[William Lee Irwin III]

This could be an artifact of the -j64 (BTW, has anyone else noticed the
makefiles can only keep 5 or 6 cpus busy at a time much of the time,
and often less?).

gcc -O   -ffunction-sections -c Text/Regex/Posix_hsc.c -o Text/Regex/Posix_hsc.o
