Subject: build-sys: fix out-of-tree build for hwclock
X-Git-Tag: v2.35-rc1~40
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=897166a86d68bdc2ac613bd14d2ffcba34410fd6;p=thirdparty%2Futil-linux.git

build-sys: fix out-of-tree build for hwclock

The file sys-utils/hwclock-parse-date.c is generated from .y and
stored in the build directory and "#include hwclock.h" is interpreted
relatively to the build tree rather than to source tree. We need
explicit -I compiler option to point to $srcdir for hwclock.
