This is libgit2.pc found on Arch Linux, whose first line prefix is quoted:

prefix="/usr"
libdir=${prefix}/lib
includedir=${prefix}/include

Name: libgit2
Description: The git library, take 2
Version: 0.27.0

Libs: -L${libdir} -lgit2
Libs.private: -lrt -lpthread -lcurl -lssh2
Requires.private: openssl zlib

Cflags: -I${includedir}

When we use pkg-config to get the value of libdir, we get the expected result:

$ ./pkg-config --variable=libdir libgit2
/usr/lib

When we use pkgconf to get the value of libdir, /usr is quoted so the result is invalid:

$ ./pkgconf --variable=libdir libgit2
"/usr"/lib

The latter result seems to cause guile-git to fail to build. This problem was reported by an Arch Linux user: https://aur.archlinux.org/packages/guile-git-lib/

Is it a bug of pkgconf, or we should ask libgit2 to stop using quotes in .pc files?
