Subject: build: let sed use posix ERE instead of GNU extension
X-Git-Tag: v22~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e414d087d90e0a6d77a12de5d4064bde5e6f116c;p=thirdparty%2Fkmod.git

build: let sed use posix ERE instead of GNU extension

Use POSIX Extended Regular Expression (ERE) instead of the GNU extension
\| in the install-exec-hook. This makes it create the symlink properly
with busybox sed built with musl libc. It will silently create a broken
symlink otherwise.

Lucas De Marchi:  fix up added newline.
