commit 53994f12633b863eb833fc3b1f6971ae8de61ff8
Author: Joseph Myers <joseph@codesourcery.com>

Make some ldbl-128, ldbl-128ibm arrays const.
I noticed that an x86_64 build of libm unexpectedly contained more
non-constant data than an older version (before _Float128 support)
did. The problem is non-const arrays in the ldbl-128 j0l and j1l
implementations; this patch makes those arrays, and the corresponding
ldbl-128ibm ones, const.
Tested for x86_64, and tested compilation for powerpc with
build-many-glibcs.py.
