Move w_lgamma_r to libm-compat-calls-auto
This patch adds the suffix "_compat" to lgamma_r wrappers and make some adjustments to #includes and Makefiles. This is a step towards deprecation of wrappers that use _LIB_VERSION / matherr / __kernel_standard functionality. Tested for powerpc64le, s390, and x86_64. * math/Makefile (libm-calls): Move w_lgammaF_r... (libm-compat-calls-auto): Here. * math/w_lgamma_r.c: Add suffix "_compat" to filename. * math/w_lgammaf_r.c: Likewise. * math/w_lgammal_r.c: Likewise. * sysdeps/ia64/fpu/w_lgammal_r.c: Likewise. * sysdeps/ia64/fpu/w_lgammaf_r.c: Likewise. * sysdeps/ia64/fpu/w_lgamma_r.c: Likewise. * math/w_lgamma_r_compat.c: New file, copied from above. * math/w_lgammaf_r_compat.c: Likewise. * math/w_lgammal_r_compat.c: Likewise. * sysdeps/ia64/fpu/w_lgamma_r_compat.c: Likewise. * sysdeps/ia64/fpu/w_lgammaf_r_compat.c: Likewise. * sysdeps/ia64/fpu/w_lgammal_r_compat.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_lgamma_r.c: Add suffix "_compat" to filename. * sysdeps/ieee754/ldbl-opt/w_lgammal_r.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_lgamma_r_compat.c: New file copied from above and adjusted for the new filenames. * sysdeps/ieee754/ldbl-opt/w_lgammal_r_compat.c: Likewise.
