weak_alias (__remainderf, remainderf)
Make drem an alias of remainder (bug 16171). The libm drem functions just call the corresponding __remainder functions. This patch removes the unnecessary wrappers by making them into weak aliases at the ELF level. Tested for x86_64, x86, mips64 and powerpc.

[NO_LONG_DOUBLE] (dreml): Define as weak alias of __remainder. * math/w_remainderf.c (dremf): Define as weak alias of __remainderf. * math/w_remainderl.c (dreml): Define as weak alias of __remainderl. * sysdeps/ia64/fpu/e_remainder.S (drem): Define as weak alias of __remainder. * sysdeps/ia64/fpu/e_remainderf.S (dremf): Define as weak alias of __remainderf. * sysdeps/ia64/fpu/e_remainderl.S (dreml): Define as weak alias of __remainderl. * sysdeps/ieee754/ldbl-opt/nldbl-remainder.c (dreml): Define as weak alias of remainderl. * sysdeps/ieee754/ldbl-opt/w_remainder.c [LONG_DOUBLE_COMPAT(libm, GLIBC_2_0)] (__drem): Define as strong alias of __remainder.
