Revert 3ea4e6f7b85f: Force autoreconf for mpfr

It breaks on my machine. Revert until we find the exact cause leading to
the initial patch, and we come up with a patch that properly fixes it.

scripts/functions: fix CT_Patch

libc/newlib: the m68k processor does not like unaligned

Disable unaligned access at least for mcpu32, m68010 and m68020.
These processors certainly do not like unaligned accesses.

scripts/functions: make CT_Patch dumber

It is the responsibility of the caller to split the package name from
its version. It already knows that.

libc/newlib: only compute version string, not full filename

debug/gdb: remove snapshot version

cc/gcc: add bugurl and compiler version to core gcc compiler

When building for bare-metal the core-gcc compiler is delivered
as final compiler, so the version info and bugurl is useful
in the core compiler as well.

binutils: allow choice for elf format when building bare-metal cross compiler

When building a baremetal cross compiler I want to be able to select
the elf format and not be forced to build the elf2flt package.

scripts: prevent trailing - in CT_TARGET

Not all target tuples consist of an VENDOR, KERNEL and SYSTEM part, build up the
tuple in such a way to no extra or trailing dashes are added to CT_TARGET
