+# Patch all .abilist files for one DSO.  The find command locates
+# abilist files for all architectures.  The regular expression in the
+# find invocation is needed to separate libc.abilist and
+# libcrypt.abilist, for example.  It assumes that abilist-pattern, if
+# set, is of the form "%-SUFFIX", and not "%SUFFIX", that is, there is
+# a non-alphanumeric seperator between the pattern and the suffix
+# added.  The abilist files in /generic/ are filtered out because
+# these are expected to remain empty.
