Subject: [PATCH] gtkdoc: fix issues that arise when cross-compiling

Specifically:
1) Make it possible to specify a wrapper for executing binaries
(usually, some kind of target hardware emulator, such as qemu)
2) Explicitly provide CC and LD via command line, as otherwise gtk-doc will
try to guess them, incorrectly.
3) If things break down, print the full command with arguments,
not just the binary name.
4) Correctly determine the compiler/linker executables and cross-options when cross-compiling

Upstream-Status: Pending
