Fix lgamma setting signgam for ISO C (bug 15421).
The lgamma (and likewise lgammaf, lgammal) function wrongly sets the signgam variable even when building for strict ISO C conformance (-std=c99 / -std=c11), although the user may define such a variable and it's only in the implementation namespace for POSIX with XSI extensions enabled. Following discussions starting at <https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems that the safest approach for fixing this particular issue is for signgam to become a weak alias for a newly exported symbol __signgam, with the library functions only setting __signgam, at which point static linker magic will preserve the alias for newly linked binaries that refer to the library's signgam rather than defining their own, while breaking the alias for programs that define their own signgam, with new symbol versions for lgamma functions and with compat symbols for existing binaries that set both signgam and __signgam. This patch implements that approach for the fix. signgam is made into a weak alias. The four symbols __signgam, lgamma, lgammaf, lgammal get new symbol versions at version GLIBC_2.23, with the existing versions of lgamma, lgammaf and lgammal becoming compat symbols. When the compat versions are built, gamma, gammaf and gammal are aliases for the compat versions (i.e. always set signgam); this is OK as they are not ISO C functions, and avoids adding new symbol versions for them unnecessarily. When the compat versions are not built (i.e. for static linking and for future glibc ports), gamma, gammaf and gammal are aliases for the new versions that set __signgam. The ldbl-opt versions are updated accordingly. The lgamma wrappers are adjusted so that the same source files, included from different files with different definitions of USE_AS_COMPAT, can build either the new versions or the compat versions. Similar changes are made to the ia64 versions (untested). Tests are added that the lgamma functions do not interfere with a user variable called signgam for ISO C, with various choices for the size of that variable, whether it is initialized, and for static and dynamic linking. The conformtest whitelist entry is removed as well. Tested for x86_64, x86, mips64 and powerpc, including looking at objdump --dynamic-syms output to make sure the expected sets of symbols were aliases. Also spot-tested that a binary built with old glibc works properly (i.e. gets signgam set) when run with new glibc.
