build: Fixes for cross-compilation. (#1527)
This commit includes two changes:
* Removes existing `AC_NO_EXECUTABLES` from `configure.ac`, since it
is a hack only intended to be used by the GCC project.
* Adds a new configure argument: `--enable-no-executables-hack`,
which restores `AC_NO_EXECUTABLES` for broken build environemnts
which require it.
* Removes `--target` from example makefiles, since it is only
appropriate when compiling compilers.
As a side effect of the second change, cross compiling with the
makefiles now no longer causes the `arm-none-eabi-` prefix to be
prepended to all built executables. This change updates all of the
documentation accordingly.
