branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master
It seems that 57e8823548ad6e65d33b2153edeb18fb0edc20e6 removed completely
sigtimedwait symbol from libc which is wrong. I hope there is not too
many other things like this.
Apparently the libc_hidden_* macros actually make previously hidden
symbols visible globally (creates alias from __GI_* to *). This is
probably ancient confusion from times when gcc did not support
visibility attribute and hiding symbols was done using hacks like
this.
This also adds attribute_hidden to the internal __sigtimedwait for
nptl case.
