Simplify the switch from uClibc to uClibc-ng.
Apps already built against uClibc-0.9.x.y require .so.0
libs to present on target which in case of current uClibc-ng is
not the case and those apps could not be run.
This change creates symlinks from .so.1 to .so.0 for
most of other libs in the same way as it was done by
23e96d89b6ab "ldso: install backward compatibility symlink by default"

_IEEE_LIBM is always defined, so the other code is never
used. I don't know when it was actively used.

Some software make use of exp10, so add it.
Basic testing with LTP.

We already provide sincos() on some archs, so we should ship a generic version.

This adds support for a new binary format, DSBT ELF, to the Makefiles.
Every shared library is assigned a DSBT index, and the link.so macro is
adjusted to ensure the correct linker argument is passed.
Configuration and ldso support will follow in separate commits.

Update the powerpc buildsys of libm to use the TARGET_SUBARCH.
Further fix the e500 Makefile.arch by adding the definition
of libm_ARCH_fpu_DIR that was actually missing.

Indeed fenv funxtions are SH4 specific, so move them into
an SH4 specific sub-folder.

Since sublevel releases are not ABI compatible we need to adjust
the soname to include the sublevel version.
This makes it possible to install ABI incompatible versions of the
library side by side so clean upgrades are possible.

so that it is easier to modify, sort, etc;
use __ in filenames of wrappers which wrap __functions
(it may be useful to have function and file names ALWAYS match);
remove names of not implemented wrappers (it was generating useless
empty .o files).
libm/ldouble_wrappers.c: comment out the wrapper which is
not compiled anyway
test/math/compile_test.c: improve this test, it was optimizing out some calls,
and we don't want that.
No actual code changes.

*: fix everything which prevents above from building

remove wrong casts to long double of long return values.
remove lots of empty lines.

This makes in possible to enable test/math

- pull replacement funcs for fpmacros.c from glibc
This removes the powerpc/classic implementation which did not state any
license but read:

and thus was dubious (and not needed).

Since there are more places which want to depend on $(libc), fix them all to
use a new variable $(libc.depend), which contains the filename for which we
have a rule.
