Gettext compilation on MSys

Trying to build gettext library on MSys I've got some errors related to pthread. Included readme states you need to have Cygwin for that. For those, who prefer MSys over Cygwin here goes a quick fix:

./configure

Add -lpthread to LIBS section in gettext-runtime/src/Makefile and gettext-tools/src/Makefile.
Remove tests target from gettext-runtime/Makefile and gettext-tools/Makefile.

make; make install

Be happy.
