b3fc562453 config/ppc: fix native build with GCC 4.8.5 on RHEL 7
The POWER meson.build file incorrectly checks if the detected CPU is
"greater than" POWER8 when it should actually test for "greater than or
equal to" POWER8.  Fixed the comparison operator.

7501968808 config/ppc: select instruction set for IBM Power10
For native build, enabling building the highest cpu_instruction_set
supported by the build host, including the new POWER10.

For cross compile, verifying that the compiler supports the
cpu_instruction_set specified in the cross-file

dfb1ad1e7a config/ppc: fix build with GCC >= 10
Like for python, multiline statements in meson must either use a
backslash character (explicit continuation) or be enclosed in ()
(implicit continuation).

python PEP8 recommends the latter [1], and it looks like meson had
an issue with backslash before 0.50 [2].

394407f50c config/ppc: ignore GCC 11 psabi warnings
Suppress the gcc warning "note: the layout of aggregates containing
vectors with 4-byte alignment has changed in GCC 5" on POWER systems
by setting "-Wno-psabi".  Warning was originally added to gcc in
commit https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=9832651 to warn
of the vector alignment changes introduced in GCC 5.  Older gcc
versions forced vector alignment to 16 bytes due to requirements for
POWER 6 and earlier CPUs, but these restrictions don't apply to CPUs
supported by DPDK.

bf66003b51 build: use platform for generic and native builds
The current meson option 'machine' should only specify the ISA, which is
not sufficient for Arm, where setting ISA implies other settings as well
(and is used in Arm configuration as such).
Use the existing 'platform' meson option to differentiate the type of
the build (native/generic) and set ISA accordingly, unless the user
chooses to override it with a new option, 'cpu_instruction_set'.
The 'machine' option set the ISA in x86 builds and set native/default
'build type' in aarch64 builds. These two new variables, 'platform' and
'cpu_instruction_set', now properly set both ISA and build type for all
architectures in a uniform manner.
The 'machine' option also doesn't describe very well what it sets. The
new option, 'cpu_instruction_set', is much more descriptive. Keep
'machine' for backwards compatibility.

5f760b7dcc config/ppc: reduce number of cores and NUMA nodes
When setting RTE_MAX_LCORES to the maximum value supported by ppc
hardware (1536), the lcores_autotest may timeout after 30 seconds
because the test takes nearly 60 seconds to complete. Set max_lcores to
a lower value because the maximum value is unlikely to be seen in any
production systems and to eliminate the quick test timeout error.

84fb33fec1 build: remove deprecated cpuflag macros
Replace use of RTE_MACHINE_CPUFLAG macros with regular compiler
macros, which are more complete than those provided by DPDK, and as such
it allows new instruction sets to be leveraged without having to do
extra work to set them up in DPDK.

dd45ed7e74 build: rename ppc sub-directories
The directories ppc_64 are renamed as ppc in
	- config/
	- lib/librte_eal/common/arch/
	- lib/librte_eal/common/include/arch/

The EAL directories are not really renamed, but symbolically linked,
because they will be moved with their new name in the next commits.

If ppc_32 needs to be supported, it can be in the same directory.
The arch directories arm and x86 are already covering both 32 and 64-bit
sub-architectures.
