- Subject: Add missing ARM CLIBABI variables __aeabi_std*
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. glibc provided most of
these (as hidden static-only symbols in the case of the variables) but was
missing __aeabi_stdin, __aeabi_stdout and __aeabi_stderr; I've applied
this patch to add these.
