Subject: Fix passing CFLAGS on the make command line.
X-Git-Tag: v1.9~84^2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4573adbe32f8a83b957ff04368c916073052a0b4;p=users%2Fsagi%2Fnvme-cli.git

Fix passing CFLAGS on the make command line.

Commit 254bcd6b2343 ("Fix CFLAGS parameter") only fixed the problem
if the variable came from the environment, not if it came from the
command line.  Fix it using 'override'.  See the GNU Make manual,
section 6.7 ("Overriding variables") for details.
