Correctly size profiling reloc table (bug 17411)

During auditing or profiling modes the dynamic loader
builds a cache of the relocated PLT entries in order
to reuse them when called again through the same PLT
entry. This way the PLT entry is never completed and
the call into the resolver always results in profiling
or auditing code running.

The problem is that the PLT relocation cache size
is not computed correctly. The size of the cache
should be "Size of a relocation result structure"
x "Number of PLT-related relocations". Instead the
code erroneously computes "Size of a relocation
result" x "Number of bytes worth of PLT-related
relocations". I can only assume this was a mistake
in the understanding of the value of DT_PLTRELSZ
which is the number of bytes of PLT-related relocs.
We do have a DT_RELACOUNT entry, which is a count
for dynamic relative relocs, but we have no
DT_PLTRELCOUNT and thus we need to compute it.

This patch corrects the computation of the size of the
relocation table used by the glibc profiling code.

	[BZ #17411]
	* elf/dl-reloc.c (_dl_relocate_object): Allocate correct amount for
	l_reloc_result.
Run tst-ld-sse-use.sh with bash.

tst-ld-sse-use.sh is a bash script, not a POSIX shell script, and so
needs to be run with $(BASH) not $(SHELL) to avoid errors of the form:

../sysdeps/x86/tst-ld-sse-use.sh: 41: ../sysdeps/x86/tst-ld-sse-use.sh: declare: not found

(when /bin/sh is dash).  This patch makes that change.

Tested for x86_64.

	* sysdeps/x86/Makefile ($(objpfx)tst-ld-sse-use.out): Run script
	with $(BASH) not $(SHELL).
