math: don't clobber old libm.so on install [BZ #19822]
When installing glibc (w/mathvec enabled) in-place on a system with a glibc w/out mathvec enabled, the install will clobber the existing libm.so (e.g., /lib64/libm-2.21.so) with a linker script. This is because libm.so is a symlink to libm.so.6 which is a symlink to the final libm-2.21.so file. When the makefile writes the linker script directly to libm.so, it gets clobbered. The simple patch below to math/Makefile fixes this. It is based on the nptl Makefile, which does exactly the same thing in a safer way.
