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.
