[PATCH] config: Add pkgincludedir to Cflags

[Namhyung Kim <namhyung@gmail.com>]

The libelf and libdw uses pkginclude_HEADERS but the pkg-config file
misses to have it the Cflags.  This was a problem for libdw users since
it gave nothing to include, but one needs to add /usr/include/elfutils
directory to use the libdw.h header file.
