configure: use AC_PATH_TOOL for pkg-config
AC_CHECK_PROGS will find the tool using exactly the name given: it
only searches for "pkg-config". When doing native builds, this is
generally fine. However, when cross-compiling, this is not ideal
as `pkg-config` is often configured for the build system, not the
system we want to cross-compile for.
Switch to using the AC_PATH_TOOL tool instead. This will look for
"pkg-config" with a $host- prefix first before falling back to the
plain "pkg-config". When doing native builds, things should still
behave the same, but now things work better out of the box when we
cross-compile.
For example, `./configure --host=aarch64-linux-gnu` will first look
for "aarch64-linux-gnu-pkg-config" before falling back to the plain
"pkg-config".
