changing optimization for crunchgen components

["Kurt J. Lidl" <lidl%pix.net@localhost>]

OK, so now I've run into a problem that I don't seen an
obvious way around...

I'm stuck trying to build the 'fsdb' pieces that will get
crunch'd and then linked together in /rescue.

(Built environment is Solaris x86, target is netbsd-5-rc3-ish,
but I don't think it matters.)

Anyway -- my gcc 4.3.3 targeted coldfire compiler is giving
up the ghost when it tries to compile fsdb.c with "-Os". [1]

If I specify "-O1", the compiler will work.

How do I set the optimization flags for just one source file of
the stuff that gets put into in the /rescue binary?

Doing what I've done in other places in sbin, and usr.bin (e.g.):

.if ${MACHINE_ARCH} == "m68k" && ${MACHINE} == "coldfire"
COPTS.fsdb.c+= -O1
.endif

This doesn't work.  The crunch compile still comes out with -Os, and
doesn't pick up my COPTS setting.  In the other places where I've
needed to override the optimization, I get "...-gcc -O2 -pipe .... -O1
" in the generated compile invocation, and gcc honors the last -O flag
on the command line, so adding the extra COPTS ends up working out
alright for me.
