Remove conditional on LDBL_MANT_DIG from e_lgammal_r.c
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. * sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgammal_r): Remove conditionals on LDBL_MANT_DIG. * sysdeps/ieee754/ldbl-128ibm/e_lgammal_r.c (__ieee754_lgammal_r): Likewise.
