Build: fix assert_boolean implementation
The current assert_boolean does not work with variables assigned with '=' flavor instead of ':='. For example, FOO = $(BAR) BAR := 1 Here, $(value FOO) is evaluated to $(BAR), not 1. This is not what we expect. While I am here, I simplified the implementation. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
