libpspell has bogus dependences that explicitely include -lc:
check out /usr/lib/libpspell.la, particularly dependency_libs. The list
includes: -L/usr/src/build/141109-i386/BUILD/pspell-.12.2/modules/.libs 
-L/usr/lib/gcc-lib/i386-redhat-linux/3.2/../../.. 

What is more important, it also includes explicitely -lc that makes it very
difficult - if not impossible - to link a threaded program.

How reproducible:
Always

Steps to Reproduce:
1. Just list the file.  or try linking a test threaded program that does fork
against this library.
	

Actual Results:  Described above.

Expected Results:  The linking order will become incorrect because libc will be
linked before libpthread, which will cause that the for example fork() function
will misteriously hang (becuse it will be taken from libc instead of libpthread).
