On s390x we're using the preprocessor for generating our linker scripts
out of assembly files. The macro `__ASSEMBLER__` is defined with value 1
when preprocessing assembly language using gcc. [1] Therefore, let's
check for the macro `__ASSEMBLER__` in `lib/linux/const.h` as well. Thus
we can use macros that makes use of the `_AC` or `_AT` macro in the
"linker scripts".
