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

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

A previous patch to headers_install.sh normalized the usage of
__ASSEMBLER__ to __ASSEMBLY__ in the UAPI headers due to the
assumption that older versions of GCC might not define __ASSEMBLER__
automatically and thus using __ASSEMBLER__ in the UAPI headers might
break compilation with very old versions of GCC. However, as we now
reassured, even GCC 2.95 still defines __ASSEMBLER__ automatically
(and even older versions are hopefully not in use with the current
Linux UAPI headers anymore).
__ASSEMBLER__ is also set automatically by other C compilers like PCC
(see https://github.com/IanHarvey/pcc/blob/cvs2git/2018.09.20/cc/cc/cc.1#L405)
and Tiny-C (see https://repo.or.cz/tinycc.git/commitdiff/a25325e9be13e52a),
so using __ASSEMBLER__ in UAPI header files should really be fine.

Thus let's head forwards and standardize on __ASSEMBLER__ instead
of __ASSEMBLY__ in the UAPI header files now.

 To avoid the churn, feel free to squash this patch with
 Thomas Weißschuh's original patch as long as it has not been
 merged to Linus' tree yet.
