[PATCH 25/33] kbuild: use POSIX BRE in headers install target

From: Mike Frysinger <vapier@gentoo.org>

The sed expression used at the moment in scripts/Makefile.headersinst
relies on the (handy) GNU extension where you can escape ERE's in an
otherwise BRE without using the GNU -r option. The following patch
replaces this "\+" usage with a functionally equivalent POSIX BRE compliant
"\{1,\}". Tested with `make headers_install` against blackfin/x86_64/i386
targets.

Stupid whiny OS X users and their crappy sed ;)
