[Driver] Properly use values-X[ca].o, values-xpg[46].o on Solaris Builtins-*-sunos :: compiler_rt_logbf_test.c currently FAILs on Solaris, both SPARC and x86, 32 and 64-bit. It turned out that this is due to different behaviour of logb depending on the C standard compiled for, as documented on logb(3M): RETURN VALUES Upon successful completion, these functions return the exponent of x. If x is subnormal: o For SUSv3-conforming applications compiled with the c99 com- piler driver (see standards(7)), the exponent of x as if x were normalized is returned. o Otherwise, if compiled with the cc compiler driver, -1022, -126, and -16382 are returned for logb(), logbf(), and logbl(), respectively. Studio c99 and gcc control this by linking with the appropriate version of values-xpg[46].o, but clang uses neither of those. The following patch fixes this by following what gcc does, as corrected some time ago in Fix use of Solaris values-Xc.o (PR target/40411) https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02350.html and https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02384.html. Tested on x86_64-pc-solaris2.11, sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu. Differential Revision: https://reviews.llvm.org/D64793 llvm-svn: 367866
