[yocto] prelink-cross project update

[Mark Hatle]

A new version of the prelink-cross has been pushed to the repository.

This version fixes a number of minor bugs found during development, it is also 
believed to resolve bug #1808 relating to ARM prelinking, and adds support for 
x86_64's x32 ABI.

Special thanks to Mentor Graphics for contributing the ARM TLS fix.

There were no upstream changes to the main prelink component, all changes are
specific to the cross functionality.  Below is the Changelog, since the last update:

         * elf.h, rtld/dl-lookupX.h, rtld/rtld.c: Sync to eglibc 2.15

         Integrate R_ARM_TLS_DESC relocation support patch:

         2011-04-13  Maciej W. Rozycki  <macro at codesourcery.com>

         * src/prelink.h (DT_TLSDESC_PLT, R_ARM_TLS_DESC): New macros.
         (DSO): Add info_DT_TLSDESC_PLT member.
         (DT_TLSDESC_PLT_BIT): New macro.
         * src/arch-arm.c (arm_prelink_rel, arm_prelink_rela): Handle
         R_ARM_TLS_DESC relocation.
         (arm_prelink_conflict_rel, arm_prelink_conflict_rela): Likewise.
         (arm_rel_to_rela): Likewise.
         (arm_undo_prelink_rel): Likewise.
         (arm_reloc_class): Likewise.
         * src/dso.c (read_dynamic): Handle DT_TLSDESC_PLT dynamic tag.

         * src/prelink.h: add missing prototypes for wrap_listxattr,
         wrap_getxattr, wrap_setxattr

2012-01-04  Mark Hatle <mark.hatle at windriver.com>
         * exec.c: Check that a section is larger then 0 bytes when
           determining the section to segment mapping.  This matches
           the behavior of elfutils - readelf.  Otherwise an empty
           PROGBITS section at the end of a segment will cause a
           failure.
