PR 29764
gas	* testsuite/gas/arm/cpu-cortex-a76ae.d: Add arm prefix to the -m
	option passed to objdump.
	* testsuite/gas/arm/cpu-cortex-a77.d: Likewise.
	* testsuite/gas/aarch64/cpu-cortex-a76ae.d: Add aarch64 prefix to
	the -m option passed to objdump.
	* testsuite/gas/aarch64/cpu-cortex-a77.d: Likewise.

bfd	* cpu-arm.c (scan): Accept machine names prefixed with "arm:".
	* cpu-aarch64.c (scan): Accept machine names prefixed with "aarch64:".

bin	* doc/binutils.texi (objdump): Note that the -m option supports
	the <architecture>:<machine> syntax.

@@ -2526,6 +2526,12 @@ can be useful when disassembling object files which do not describe
architecture information, such as S-records. You can list the available
architectures with the @option{-i} option.
For most architectures it is possible to supply an architecture
name and a machine name, separated by a colon. For example
@samp{foo:bar} would refer to the @samp{bar} machine type in the
@samp{foo} architecture. This can be helpful if objdump has been
configured to support multiple architectures.
If the target is an ARM architecture then this switch has an
additional effect. It restricts the disassembly to only those
instructions supported by the architecture specified by @var{machine}.
