Subject: change default CFLAGS settings into the default
X-Git-Tag: v1.1~6^2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9c4f79fe0c9aa4d05f82c0f34cd4956bf76549e8;p=users%2Fsagi%2Fnvme-cli.git

change default CFLAGS settings into the default

The way compiler settings are appended to CFLAGS breaks custom flags
that people are using to build.  So if someone does:
	$ export CFLAGS='-O0 -ggdb'
	$ make
The build will force -O2 instead.

Shift these defaults into a default setting rather than always appending.
