Subject: dev.mk.in: Fix file name too long error
X-Git-Tag: v3.7~76
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fcdf02dfd7e77c6054080c410aacb93ab0cfffcd;p=thirdparty%2Fccache.git

dev.mk.in: Fix file name too long error

The all_cppflags changes path to filename which causes file name too long
error when the path is longer than NAME_MAX (usually 255). Strip srcdir
to fix the problem.
