Subject: package/libv4l: add optional support for alsa-lib
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a6af4471f081a2a40f41c644cb0d54eceee3dd1f;p=buildroot.git

package/libv4l: add optional support for alsa-lib

Add alsa-lib as optional dependency to get a reproducable build.
Without this patch configure logs:

checking for ALSA... no
configure: WARNING: ALSA library not available

After this patch alsa-lib was built before libv4l:
checking for ALSA... yes
