H A Dtest-all.c8a1b1718 Tue Mar 12 00:30:48 CDT 2019 Song Liu <songliubraving@fb.com> perf build: Check what binutils's 'disassembler()' signature to use

Commit 003ca0fd2286 ("Refactor disassembler selection") in the binutils
repo, which changed the disassembler() function signature, so we must
use the feature test introduced in fb982666e380 ("tools/bpftool: fix
bpftool build with bintutils >= 2.9") to deal with that.

Committer testing:

After adding the missing function call to test-all.c, and:

FEATURE_CHECK_LDFLAGS-disassembler-four-args = -bfd -lopcodes

And the fallbacks for cases where we need -liberty and sometimes -lz to
tools/perf/Makefile.config, we get:

$ make -C tools/perf O=/tmp/build/perf install-bin
make: Entering directory '/home/acme/git/perf/tools/perf'
BUILD: Doing 'make -j8' parallel build
