Most pkgconfig files contain a Libs: variable, which is either /usr/lib
or /usr/lib64. If a 32bit and a 64bit variant of fmt libraries is
installed, the last one wins. As a result compiling for the other
bitsize will fail.

Instead of sharedir use libdir as install target.

* Added missing typename to FMT_STRING.

This is so that FMT_STRING can be used in a template.
