Joseph Myers ea41469b7a Fix profil_counter namespace (bug 17725).
On ARM, where profil_counter is not static, it is brought in by
references to various standard functions, as noted in
<https://sourceware.org/ml/libc-alpha/2014-11/msg00890.html>, although
it is not a standard function itself.  I don't know if this also
causes test failures on SPARC, although I see no reason for it not to
do so.

This patch fixes this namespace issue.  profil_counter is renamed to
__profil_counter and made a weak alias on ARM and SPARC.  Because of
the uses in profil.c / sprofil.c it seems simplest to make the rename
globally, including on the other architectures for which
profil_counter was static and so the change is of no substance.  The
variant names profil_counter_* used in sprofil.c are also renamed to
start with __ so that undesired function names do not get exported in
static libc.

As I noted in bug 17726, profil_counter should probably be a compat
symbol on ARM and SPARC, so it wouldn't exist at all in static libc
even as a weak alias.  Since defining a compat symbol still requires
an internal name as a target of an alias, this patch still seems
reasonable as an intermediate step towards that goal: it wouldn't be
possible for the function simply to be static profil_counter on ARM
and SPARC with profil_counter also being the exported compat symbol
name, so profil.c / sprofil.c would still need to be prepared to call
the function under another name (here, __profil_counter).

Tested for x86_64 (testsuite, and that stripped installed shared
libraries are unchanged by the patch) and ARM (ABI and linknamespace
tests - this patch reduces the number of linknamespace failures I see
on ARM from 227 to 5, the residue being math.h failures for fe*
functions and for j0l/j1n/jnl/y0l/y1l/ynl aliases).
