Subject: configure: move CFLAGS/CPPFLAGS to LLDP_CFLAGS/LLDP_CPPFLAGS
X-Git-Tag: 0.7.14~33
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d627ab691987bc8c76be17917fd4dc2a608ba8ef;p=thirdparty%2Flldpd.git

configure: move CFLAGS/CPPFLAGS to LLDP_CFLAGS/LLDP_CPPFLAGS

The goal is to avoid the user to override those flags when using `make
CFLAGS=somethingelse`. This is to enable a user to use `make
CFLAGS=-Werror` since this flag cannot be used with `./configure`.
