Make armv6 hard float abi by default. Kill armv6hf.
...
Allow CPUTYPE=soft to build the current soft-float abi libraries.
Add UPDATING entry to announce this.

Clean up detection of hard-float ABIs. As with big-endian in r272368 we
...
can check against arm*hf*.

Remove MK_ARM_EABI, the armeb issues have been fixed. The code to support
...
the oabi is still in the tree, but it is expected this will be removed
as developers work on surrounding code.
With this commit the ARM EABI is the only supported supported ABI by
FreeBSD on ARMa 32-bit processors.

Add the fp{get,set}{mask,round} functions to the public symbols in the map.
...
These are only exported for armv6hf as the soft-float ABIs have these in
the softfloat Symbol.map file.

Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}
...
if not already defined. This allows building libc from outside of
lib/libc using a reach-over makefile.
A typical use-case is to build a standard ILP32 version and a COMPAT32
version in a single iteration by building the COMPAT32 version using a
reach-over makefile.

Add the required __aeabi_* functions to libc.
...
The floating point functions are here rather than compiler-rt because the
libc softfloat code allows us to set the rounding mode.

Use GCC's __SOFTFP__ to test whether we're being compiled
...
with softfloat or not. Now -msoft-float can be overridden
more easily.

Eliminate gdtoa.mk and move its contents to ${MACHINE_ARCH}/Makefile.inc.
...
The purpose of having a separate file involved an abandoned scheme that
would have kept contrib/gdtoa out of the include path for the rest of libc.
