[git commit] Add missing CLIBABI variables __aeabi_stdin, __aeabi_stdout, __aeabi_stderr.

[Joseph Myers]

commit: http://git.uclibc.org/uClibc/commit/?id=60e244a98fbaa4c8637dd1c3147979633e5179aa
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master


The ARM EABI has a document CLIBABI specifying various __aeabi_*
functions and variables to be provided for the use of portable objects
that can be linked with different EABI-conforming C libraries.
__aeabi_stdin, __aeabi_stdout and __aeabi_stderr were missing in
uClibc; this patch (originally from Nathan Froyd and for glibc) adds
them.
