Generally, throughout the port, make sure comments end ". " (full stop,
two spaces, end of comment). I won't remark on other places with this
formatting issue.

As a new port I think it would be best to use init_array in your Implies
file so you don't need these crti / crtn files, and make GCC generate
init_array / fini_array exclusively. (See RISC-V and C-Sky discussions of
this issue.)

Except for the multiple-include guards round a whole header file,
preprocessor directives inside #if should have indentation in glibc, so
"# define" (and "# define" inside two levels of #if, etc.). (As usual,
fix this throughout the port; I won't list other individual places with
this issue.)

Note the first letter of a comment should be capitalized (in addition to
ending with ". ").

glibc style uses "unsigned long int", not just "unsigned long".

Any file more than ten lines long should have copyright and license
notices.
