drop support for pre ISO-C compilers

This drops __signed, __volatile, and __const.  Only the latter was
used in the code base, and for uClibc, not consistently.  Much of
the code used plain "const" which meant "__const" was useless.

Really, the point of this is to stay in sync with what glibc did.
