The IEEE 754 implementation of lgammal in sysdeps/ieee754/ldbl-128/ used
to be shared by IBM's implementation in sysdeps/ieee754/ldbl-128ibm/ (by
an inclusion of the source file). In order for the algorithm to work
for IBM's implementation, a check for LDBL_MANT_DIG was required. Since
the source file is no longer shared, the requirement for the check is
gone. This patch removes the conditionals.
Tested for powerpc64le and s390x.
