c5a13efa9b Added test for ifunc support in dynamic linker. 
ifuncs now work in i386 and x86_64 when called in the same library as
well as in a different library.

0266ae5f88 Switch <elf.h> over to linux uapi under the covers. 
Remove the linker's reliance on BSD cruft and use the glibc-style
ElfW macro. (Other code too, but the linker contains the majority
of the code that needs to work for Elf32 and Elf64.)

All platforms need dl_iterate_phdr_static, so it doesn't make sense
to have that part of the per-architecture configuration.

2c5153b043 libc: add getauxval() 
Add support for getauxval().  This method allows a program an easy way
to retrieve information from the kernel auxiliary vector, and will
hopefully replace other clumsy ways of accessing this same information.

This particular function was also added to glibc in glibc 2.16.
See the following URLs for more details.

  * http://www.gnu.org/software/libc/manual/html_node/Auxiliary-Vector.html

This change is a prerequisite for bug 7959813.

67e7a93844 Eliminate duplicate constants 
include/elf.h contains basically the same values as
linux/auxvec.h. Eliminate dups.

include/sys/exec_elf.h contains basically the same
values as linux/elf.h. Eliminate dups.
