Debian squeeze has libcheck.a and libcheck_pic.a, but no
libcheck.so in package 'check'.

There are other files names *_pic.a, and obviously those
libraries are to be linked to a PIE. If I use -lcheck_pic,
building PIEs works.

Maybe configure must be extended to try library names
with an additional _pic for PIE.
