X-Git-Tag: ppp-2.4.8~13

pppd: Fix variable reference syntax in Makefile.linux

References to the variable called CC in makefiles need to be
written as $(CC) not $CC.  Make interprets the latter as a reference
to the (nonexistent) variable C followed by a literal C.

Fixes: 4e713175 ("make: Avoid using host include for cross-compiling")
