The "x86 instruction decoder - new instructions" test takes up space but
is only really useful to developers. Make it optional at build time.
Add variable EXTRA_TESTS which must be defined in order to build perf
with the test.
Example:
Before:
$ make -C tools/perf clean >/dev/null
$ make -C tools/perf >/dev/null
Makefile.config:650: No libunwind found. Please install libunwind-dev[el] >= 1.1 and/or set LIBUNWIND_DIR
Makefile.config:1149: libpfm4 not found, disables libpfm4 support. Please install libpfm4-dev
PERF_VERSION = 6.4.rc3.gd15b8c76c964
$ readelf -SW tools/perf/perf | grep '\.rela.dyn\|.rodata\|\.data.rel.ro'
[10] .rela.dyn RELA 000000000002fcb0 02fcb0 0748b0 18 A 6 0 8
[18] .rodata PROGBITS 00000000002eb000 2eb000 6bac00 00 A 0 0 32
[25] .data.rel.ro PROGBITS 00000000009ea180 9e9180 04b540 00 WA 0 0 32
After:
$ make -C tools/perf clean >/dev/null
$ make -C tools/perf >/dev/null
Makefile.config:650: No libunwind found. Please install libunwind-dev[el] >= 1.1 and/or set LIBUNWIND_DIR
Makefile.config:1154: libpfm4 not found, disables libpfm4 support. Please install libpfm4-dev
PERF_VERSION = 6.4.rc3.g4ea9c1569ea4
$ readelf -SW tools/perf/perf | grep '\.rela.dyn\|.rodata\|\.data.rel.ro'
[10] .rela.dyn RELA 000000000002f3c8 02f3c8 036d68 18 A 6 0 8
[18] .rodata PROGBITS 00000000002ac000 2ac000 68da80 00 A 0 0 32
[25] .data.rel.ro PROGBITS 000000000097d440 97c440 022280 00 WA 0 0 32
Committer notes:
Build with 'make EXTRA_TESTS=1 -C tools/perf O=/tmp/build/perf" and
reproduced the ELF section size differences.
