tools: kwbimage: Allow disabling build on non-mvebu platforms
Some users want to build with CONFIG_TOOLS_LIBCRYPTO disabled, which in
general is possible for at least some boards. 32-bit mvebu however
requires kwbimage for building SPL, and kwbimage has a hard dependency
to host OpenSSL.
The new symbol CONFIG_TOOLS_KWBIMAGE allows disabling kwbimage build on
non-mvebu platforms, and thus building without host libcrypto from
OpenSSL.
Based on previous work and discussions, see links below.
