Subject: replace armhf math asm source files with inline asm

this makes it possible to inline them with LTO, and is the simplest
approach to eliminating the use of .sub files.

this also makes VFP sqrt available for use with the standard EABI
(plain arm rather than armhf subarch) when libc is built with
-mfloat-abi=softfp. the same could have been done for fabs, but when
the argument and return value are in integer registers, moving to VFP
registers and back is almost certainly more costly than a simple
integer operation.
