* support cross-compiling an x86-64 target on an arm64 host. This
it turns out is a matter of *removing* an unnecessary dependency.
(aarch64-linux-gnu-pkg-config exists but x86_64-linux-gnu-pkg-config
doesn't. Turns out neither is necessary.) Added a comment explaining
where ${gcc_target}-pkg-config comes from now.
* documentation tweaks
* improve debug output a bit
