If the target machine has SVE feature (e.g. "-march=armv8.2-a+sve'),
and the compiler is gcc-8.3, it will produce this error:
In file included from lib/eal/common/eal_common_options.c:38:
lib/eal/arm/include/rte_vect.h:13:10: fatal error:
arm_sve.h: No such file or directory
#include <arm_sve.h>
^~~~~~~~~~~
The root cause is that gcc-8.3 supports SVE (the macro
__ARM_FEATURE_SVE was 1), but it doesn't support SVE ACLE [1].
The solution:
a) Detect compiler whether support SVE ACLE, if support then define
RTE_HAS_SVE_ACLE macro.
b) Use the RTE_HAS_SVE_ACLE macro to include SVE header file.
[1] ACLE: Arm C Language Extensions, the SVE ACLE header file is
<arm_sve.h>, user should include it when writing ACLE SVE code.

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
