Subject: sysd-rules: Cut down the number of rtld-% pattern rules
X-Git-Tag: glibc-2.25~524
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e68c8d2757f05d1817d95d66cd3f2c2acc538b34;p=thirdparty%2Fglibc.git

sysd-rules: Cut down the number of rtld-% pattern rules

rtld only needs shared objects, so the other patterns are pointless and
significantly increase the work make has to perform while identifying
which pattern rule to apply.
