With .devel, add -g3 for MIPS C and DEC C.

Lifted from the libpcap configure script, which adds -g even without
.devel, presumably so that programs linked with libpcap can get
debugging symbols.

Those compilers are for dead OSes (IRIX, Tru64 UNIX); we should probably
do whatever voodoo is needed to get Sun^WOracle C, IBM's C compiler for
AIX, and HP C to build optimized with debug symbols.
