infra: fix autotools .la fixing when no .la files are present

Browse Source 
Commit 6f638ea9c9c7bacc646430a74ad3dd2740eae676 ("infra: /usr support:
STAGING_DIR can be outside BASE_DIR") changed a for-construct around 'sed
-i' in a 'find | xargs sed -i'. However, if the find returns no results,
sed complains with:
    '/bin/sed: no input files'

This commit adds the extra parameter -r / --no-run-if-empty to the xargs
call, effectively fixing this problem case.
