[PATCH] scripts: headers_install.sh: Normalize __ASSEMBLY__ to __ASSEMBLER__

[Thomas Weißschuh]

There is an ongoing effort to replace the usage of __ASSEMBLER__ with
__ASSEMBLY__ throughout the kernel tree, see for example
commit 287d163322b7 ("arm64: Replace __ASSEMBLY__ with __ASSEMBLER__ in
non-uapi headers"). The latter is automatically provided by all compilers
and preprocessors supported by the kernel, so the explicit definitions
of __ASSEMBLER__ can be removed.

However the UAPI headers might be used with older (< GCC 3.0) or
non-GCC-compatible compilers, which do not define __ASSEMBLY__
automatically. So this migration may brake users.
Also during the migration phase, the UAPI headers will use a mix of
*both* __ASSEMBLY__ and __ASSEMBLER__ at the same time, which is ugly.

For now make sure that the exported UAPI headers consistently use
__ASSEMBLER__ as before.

This should go either through kbuild or asm-generic, I think.
