Verlihub plugins fail to compile

[Francisco Blas Izquierdo Riera (klondike)]

Binary package hint: verlihub

Compilation of verlihub plugins fails due to a bad library parameter.

When compiling, plugins usually call "/usr/bin/verlihub_config" to get the proper CFLAGS, but verlihub_config returns a bad library dir flag for verlihub libs as they are placed into /usr/lib/verlihub and not /usr/lib.

Replacing all ocurrences of "-L$prefix/lib -lverlihub" to "-L$prefix/lib/verlihub -lverlihub" in "/usr/bin/verlihub_config" seems to solve the problem.
