Subject: stdlib: Remove mp_clz_tab.c
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=036196962b6e936e150ccccce9222ae4f35fcd20;p=thirdparty%2Fglibc.git

stdlib: Remove mp_clz_tab.c

The count_leading_zeros is not used anymore, so there is no need to
provide the table for possible usage.  The hppa already provides
the compat symbol on libgcc-compat.c.
