[PATCH, cross prelink] 0001-Pull-ld.so-s-name-from-PT_INTERP-to-avoid-the-runtim.patch

[Maxim Kuvyrkov]

Mark,

This patch makes rtld emulator in cross prelink use ld.so's name as it is encoded in PT_INTERP header.

Currently, rtld emulator returns "lib/ld.so.1" for runtime linker's name, but the linker actually expects "/lib/ld.so.1" -- that one slash at the beginning causes prelink checks done by the runtime linker to fail and not use prelink information.

The runtime linker sets up a map for itself under the name stored in PT_INTERP header of the executable, and this patch makes rtld emulator follow the suit.

I have tested this patch using a different version of rtld emulator (the one that CodeSourcery / Mentor maintains), but the function in question is the same in both, so this patch is also relevant for Yocto's prelink.

Any comments?  Please merge at your leisure.

Thank you,
