[Bug libc/4457] New: Allow ports a simple override of "libgcc_s.so.1" in sysdeps/generic/framestate.c

[carlos at systemhalted dot org]

The file sysdeps/generic/framestate.c has a hardcoded value of "libgcc.so.1".
Some architectures have bumped the so version on libgcc_s and therefore the
hardcoded value is wrong.

It would be nice if ports could write:
ports/sysdeps/$target/framestate.c:
#define LIBGCC_S_SO "libgcc_so.so.2"
#include-next <framestate.c>

There are other alternatives but this one seemed the simplest and easiest to
maintain.

Patch attached.

framestate.c is so short that I wonder if it isn't better just to duplicate
the file in ports.

Another attempt

Hello,

The attached patch makes another attempt to fix this issue.

It doesn't implement exactly the solution Ulrich proposed above in that it
doesn't detects the version of libgcc_s.so installed.  Instead, the patch make
GLIBC to rely on shlib-versions files to specify it.

The entry in top-level shlib-versions file specifies the version of libgcc_s to
be '1' (what most architectures have) and shlib-versions in sysdeps directories
can override that.

FWIW, making GLIBC to autodetect the version of libgcc_s installed does not
seem trivial to me.

Set libgcc_s' version for m68k and hppa

This patch sets libgcc_s' version to 2 for m68k and to 4 for hppa.

The combined patch was tested on m68k and powerpc.

This is now fixed on trunk by these patches. 

This fix will be part of 2.11 given that the 2.11 branch happens from trunk.

Per the new bugzilla procedure I've opened new issues for m68k and hppa to
provide libgcc_s.h.
