thread testcase compile issue (question)

When I execute tests under gdb.threads/ directory for instance killed.exp,
I see 2 complies of the same testcase, the first one gets a linker error
/usr/bin/ld: cannot find -lpthreads but the second time it works with no
errors. Anyone has any idea why???

Here is the output on x86 for you to compare:

=== gdb tests ===

Schedule of variations:

Running target unix

cription file for target.
Using /home/manjo/projects/gdb/june/src/dejagnu/config/unix.exp as generic

face file for target.
Using ./config/unix.exp as tool-and-target-specific interface file.
