This is wrong. Subprojects should use /usr/bin/ and /usr/share/man/ and
not rely on the output of `git --exec-path` and so on.

For example if the user has installed Git in his $home, when building a
package the package manager would use ~/libexec/git-core, which is
wrong.

Moreover, if you are cross-compiling you won't be able to run the
target's `git` binary.

If anything, it should be `pkg-config --variable=exec-path git`.
