Subject: [PATCH] kselftest: alsa: handle cross compilation

Calling just `pkg-config` is adequate for native builds, but finding the
foreign libraries with pkg-config needs pkg-config to be called via its
architecture-specific wrapper. This works in Debian, where there is a
corresponding *-pkg-config wrapper script for each enabled foreign
architecture, just like there are *-gcc, *-ld.
