* sysdeps/i386/i686/multiarch/strcpy-ssse3.S: Fix wrong copying
processing for last bytes.
2011-12-22 Joseph Myers <joseph@codesourcery.com>
* sysdeps/unix/sysv/linux/Makefile (syscall-list-variants)
(syscall-list-default-options, syscall-list-default-condition)
(syscall-list-includes): Define.
($(objpfx)syscall-%.h $(objpfx)syscall-%.d): Support arbitrary
list of ABIs and options and #if conditions for each ABI. Do not
handle common syscalls between ABIs specially.
* sysdeps/unix/sysv/linux/powerpc/Makefile (64bit-predefine):
Remove.
(syscall-list-variants, syscall-list-32bit-options)
(syscall-list-32bit-condition, syscall-list-64bit-options)

# Generate the list of SYS_* macros for the system calls (__NR_* macros).
# For bi-arch platforms, the CPU/Makefile defines {32,64}bit-predefine and
# we generate a file that uses <bits/wordsize.h>.
# If there is more than one syscall list for different architecture
# variants, the CPU/Makefile defines syscall-list-variants to be a
# list of names for those variants (e.g. 32bit 64bit), and, for each
# variant, defines syscall-list-$(variant)-options to be compiler
# options to cause <asm/unistd.h> to define the desired list of
# syscalls and syscall-list-$(variant)-condition to be the condition
# for those options to use in a C #if condition.
# syscall-list-includes may be defined to a list of headers to include
# in the generated header, if the default does not suffice.
