Subject: [PATCH] selftest: alsa: check if user has alsa installed
Currently, if alsa development package is not installed on the user's
system then the make command would print a `pagefull` of errors. In
particular one error message is repeated 3 times. This error is returned
by `pkg-config` and since it is not being handeled appropriately,
repeated calls to `pkg-config` prints the same message again.
This patch adds check for alsa package installation. If alsa is not
installed, a short and consize error is returned. Also, it does not
affect the compilation of other tests.
