pcre @8.32: libtool file breaks clang builds by adding the -pthread option

Description
/opt/local/lib/libpcre.la contains the line:
inherited_linker_flags=' -pthread'
This option is only valid for gcc, so when clang sees it, it emits a diagnostic. This can break the build of software that uses libpcre (especially when building with warnings as errors).
This only started happening recently, maybe around MacPorts 2.1.3. The workaround is to edit libpcre.la to remove the additional option, but it takes some time to figure out what the problem is.

Fixed in r102473. Not sure why PCRE does this, since libSystem already provides the pthreads API. GCC doesn’t need the flag either.

Oops; as you mentioned in the ticket, the libtool files record the linker flags. Revbumped in r102474.

Thanks, I’ll look into this shortly.
