[email@example.com: Re: [PATCH] Bug-compatibility with Sol* ld.so]
We should make sure to pick up the glibc patch that Jakub is talking
about here; presumably it will be in 2.3, but this is something to keep
in mind if there is another 2.2 release. Which there needs to be,
since I promised to do it last weekend and didn't have time.
This only affects if glibc is _built_ with a newer version of binutils
than currently in the archive; that is, it's not a problem for

Only ld.so is affected (ie. if you build glibc < CVS today with binutils
>= CVS today, ld.so will die).
It relied on the addend being in *r_offset in:
/* Return the run-time load address of the shared object. */
static inline Elf32_Addr
register Elf32_Addr pc __asm("%o7"), pic __asm("%l7"), got;
/* Utilize the fact that a local .got entry will be partially
initialized at startup awaiting its RELATIVE fixup. */
: "=r"(pc), "=r"(got) : "r"(pic));
return pc - got;
