Comment(by dsd):

 When compiling busybox (by hand) inside mock f18 root with gcc-4.8 and
 glibc compiled with -march=iwmmxt2, I frequently see these errors:

 {{{
 rm: error while loading shared libraries: cannot create capability list:
 Cannot allocate memory
 }}}

 When it happens, running "make" again (i.e. retrying the command) tends to
 avoid the issue. Need to double check that these errors are directly
 introduced due to the iwmmxt2-enabled glibc.

 Compiling busybox with -march=iwmmxt2 in this environment results in a
 binary that fails to run with:
 {{{
 error while loading shared libraries: unexpected reloc type 0x1c
 }}}
 Need to verify if that failure is caused by the -march=iwmmxt2 flag or
 not.

 busybox config used: http://dev.laptop.org/~dsd/20120922/busybox-config

 iwmmxt2-enabled glibc:
 http://dev.laptop.org/~dsd/20120922/glibc-2.16-11.fc18.dsd4.armv7hl.rpm
