digital signature support

I just upgraded clamav to clamav-0.88.2_1 
and noticed that the make script did not recognize the GMP library
properly.

In the configure script the following line appeared

configure: WARNING: ****** GNU MP 2 or newer NOT FOUND - digital signature
support will be disabled !


as a result in the logs it now shows 
SECURITY WARNING: NO SUPPORT FOR DIGITAL SIGNATURES

I have libgmp installed and it obviously didn't find it properly.
libgmp-4.2.1        A free library for arbitrary precision arithmetic

I've been running clamav for many years and apparently there is a problem
with this latest build recognizing libgmp.
