String routines for ARM and licensing

[Roland McGrath]

In general, all contributions to glibc require an FSF copyright
assignment.  We do not include code with copyright owners other than
FSF except in special situations.  Intel supplies optimized string
functions for their new processors too, and they have assigned
copyright to FSF for those contributions.  You can too.

Note that it is easy to produce a glibc add-on that supplies new
sysdeps/ file implementations such as these.  If you won't meet the
requirements to contribute your code to glibc directly, you can
distribute it separately and encourage ARM users and system builders
to build glibc with your add-on.  That is also an easy way to make it
available for others to test and use before you have worked out the
details about contributing it to glibc or not.

Also note that ARM is maintained in libc-ports, and the correct
mailing list to discuss ARM glibc technical details with the ARM port
maintainers is <libc-ports@sourceware.org>, not this mailing list.


Thanks,
Roland
