Unable to bootstrap gcc snapshot of 20001211 on Dynix/ptx

Unfortunately, this is a longstanding bug (most of this year) in
GCC that affects DWARF-1 targets like yours.  It's testsuite entry
gcc.dg/20000503-1.c.  You can circumvent this by doing a make bootstrap
BOOT_CFLAGS=-O2, but this makes it impossible to debug GCC itself.

This shouldn't be necessary any more, as it's autoconf-detected now.

Why is this necessary?
