Features in FEATURE_TESTS_BASIC will be set as being available if
test-all.c builds, so since the rust test isn't included in test-all.c,
we can't have 'rust' in there, remove it from FEATURE_TESTS_BASIC and
use feature-check so that it tries to build test-rust.bin, doing the
actual feature detection.
On a system lacking a rust compiler:
Makefile.config:1158: Rust is not found. Test workloads with rust are disabled.
Auto-detecting system features:
... libdw: [ on ]
... glibc: [ on ]
... libelf: [ on ]
... libnuma: [ on ]
... numa_num_possible_cpus: [ on ]
... libpython: [ on ]
... libcapstone: [ on ]
... llvm-perf: [ on ]
... zlib: [ on ]
... lzma: [ on ]
... bpf: [ on ]
... libaio: [ on ]
... libzstd: [ on ]
... libopenssl: [ on ]
... rust: [ OFF ]
$ cat /tmp/build/perf-tools-next/feature/test-rust.make.output
/bin/sh: line 1: rustc: command not found
$ file /tmp/build/perf-tools-next/feature/test-rust.bin
/tmp/build/perf-tools-next/feature/test-rust.bin: cannot open `/tmp/build/perf-tools-next/feature/test-rust.bin' (No such file or directory)
$
$ perf -vv | grep RUST
rust: [ OFF ] # HAVE_RUST_SUPPORT
$
And after installing it:
... rust: [ on ]
$ cat /tmp/build/perf-tools-next/feature/test-rust.make.output
$ file /tmp/build/perf-tools-next/feature/test-rust.bin
/tmp/build/perf-tools-next/feature/test-rust.bin: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=9c416edf673ee3705b97bae893a99a6fcf1ee258, for GNU/Linux 3.2.0, with debug_info, not stripped

$ perf -vv | grep RUST
