configure script try to find a usable regular expression library.

        auto,pcre,posix,regcmp,re_comp,regcomp,regcomp-local

Default is auto and from original PR,

>>> cc -I. -c -DSYSDIR=\"/usr/local/pkg/bin\"   -O2 search.c
>>> cfe: Error: search.c: 47: Cannot open file pcre.h for #include

It seems that none-existing pcre was detected, it's really strange.
What is usable regular expression on IRIX?

Anyway, adding buildlink to pcre cause needless dependency. 
Another way is adding "--with-regex=posix" to CONFIGURE_ARGS.
(But, I don't know "posix" is usable on all platform...)
