libstdc v3 & multilibs

[Robert Lipe <robertlipe at usa dot net>]

With the fix from this morning to circumvent the 'ar', SVR5 now builds
again.  (Thanx!) I haven't tried running the tests.  But OpenServer
(which uses multilibs - highlighting the build performance problems I
mentioned earlier) still tanks during the build.

i686-pc-sco3.2v5.0.6/{coff,pic}/config.cache contain a higly suspicious
looking construct:

[ ... ] 
libiberty_cv_var_sys_errlist=${libiberty_cv_var_sys_errlist='yes'}
libiberty_cv_var_sys_nerr=${libiberty_cv_var_sys_nerr='yes'}
libiberty_cv_var_sys_siglist=${libiberty_cv_var_sys_siglist='no'}
lt_cv_cc_needs_belf=${lt_cv_cc_needs_belf='yes'}

Clearly, this can't be good. :-) The same system, on a target w/o
multilibs doesn't trigger this.  While I can't (yet) prove that it's
multilib related, years of being spanked by multilibs has taught me to
blame them for lots of my ills.

Since I've had such great luck with this doday, I'll ask if anyone
recognizes this or has any advice where to start digging.




Here's the output of a 'make'.
