package/elf2flt: Remove Config.in.host

Browse Source 
There is no need to have configuration files direbtly set the
BR2_PACKAGE_HOST_ELF2FLT option. The need for the elf2flt utility is
automatically determined by gcc build in package/gcc/gcc.mk according to
the BR2_BINFMT_FLAT option.

Accordingly, we can remove the file package/elf2flt/Config.in.host to
get rid of the BR2_PACKAGE_HOST_ELF2FLT option. BR2_STRIP_strip
dependency on this option is replaced with a dependency on
BR2_BINFMT_ELF.

To stay consistent with the fact that elf2flt supports only the arm, sh,
sparc, xtensa and riscv-64 architectures, a dependency on these
architectures is added to the BR2_BINFMT_FLAT option in arch/Config.in.

Board configuration files setting the BR2_PACKAGE_HOST_ELF2FLT option
are also updated.

uCLinux uses a Binary Flat format commonly known as BFLT. It
is a relatively simple and lightweight executable format
based on the original a.out format.
This option compiles the required tools and makes the required
modifications on your toolchain (linker).
