Make some ldbl-128, ldbl-128ibm arrays const.

Browse Source 
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.
