aarch/fpu: use generic builtins based math functions
introduce sysdep header math-use-builtins.h to replace aarch64 implementations with corresponding generic ones. - newly inroduced generic sqrt{,f}, fma{,f} - existing floor{,f}, nearbyint{,f}, rint{,f}, round{,f}, trunc{,f} - Note that generic copysign was already enabled (via generic math-use-builtins.h) now thru sysdep header Tested with build-many-glibcs for aarch64-linux-gnu This is a non functional change and aarch64 libm before/after was byte invariant as compared below: | cd /SCRATCH/vgupta/gnu/install-glibc-A-baseline | for i in `find . -name libm-2.31.9000.so`; do | echo $i; diff $i /SCRATCH/vgupta/gnu/install-glibc-C-reduce-scope/$i ; | echo $?; | done | ./aarch64-linux-gnu/lib64/libm-2.31.9000.so | 0 | ./arm-linux-gnueabi/lib/libm-2.31.9000.so | 0 | ./x86_64-linux-gnu/lib64/libm-2.31.9000.so | 0 | ./arm-linux-gnueabihf/lib/libm-2.31.9000.so | 0 | ./riscv64-linux-gnu-rv64imac-lp64/lib64/lp64/libm-2.31.9000.so | 0 | ./riscv64-linux-gnu-rv64imafdc-lp64/lib64/lp64/libm-2.31.9000.so | 0 | ./powerpc-linux-gnu/lib/libm-2.31.9000.so | 0 | ./microblaze-linux-gnu/lib/libm-2.31.9000.so | 0 | ./nios2-linux-gnu/lib/libm-2.31.9000.so | 0 | ./hppa-linux-gnu/lib/libm-2.31.9000.so | 0 | ./s390x-linux-gnu/lib64/libm-2.31.9000.so | 0 Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
