I wrote a configure.ac (below), use autoreconf --install
Everything runs fine if I use
CC=gcc CFLAGS="" LDFLAGS="" ./configure
But if I use

I get a linking problem.

I can't figure out where the pthread is come from.
If it is not hard-coded in the configure script, then the most likely
place it comes from is a library used in your link which uses threads,
but which was built with GCC rather than the Sun compiler. Libtool
stores the -pthread option in the installed .la file. The .la files
are just ASCII text so you can easily inspect their content.
