Mark internal gmp functions with attribute_hidden [BZ #18822]
Mark internal gmp functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/gmp.h: Declare internal functions only if _ISOMAC is undefined. (__mpn_extract_double): Add attribute_hidden. (__mpn_extract_long_double): Likewise. (__mpn_extract_float128): Likewise. (__mpn_construct_float): Likewise. (__mpn_construct_double): Likewise. (__mpn_construct_long_double): Likewise. (__mpn_construct_float128): Likewise.
