Install libm.a as linker script (bug 20539).
Install libm.a as linker script to avoid static link fail w/o passing additional -lmvec option while building with GCC >= 6.1. [BZ #20539] * math/Makefile (install-lib-ldscripts): Add libm.a. (install_subdir): Remove. (install-others): Add. ($(inst_libdir)/libm.a): Add rule for installation as linker script. * Makerules (install-lib.a): Filter out install-lib-ldscripts.
