+Subject: install pkg-config file into libdir
+
+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.
+
+Fixes commit 9d0c9c4bb145a286f725cd38c90331eee7addc7f
+Fixes commit 287342dab10a5a96479b3e21cd11ce671ed8125c
