Subject: Makefile: improve detection of make "-s" flag
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fffb68a83fde238523d330fc8ada63580bbc46a8;p=buildroot.git

Makefile: improve detection of make "-s" flag

Because it's just checking the presence of the "s" character even a
  make --warn-undefined-variables
is detected as a silent build.

Fix that by filtering out long options.
