For the particular case that our systems detected, CC is set to the following: export CC="aarch64-linaro-linux-gcc --sysroot=/oe/build/tmp/work/machine/perf/1.0-r9/recipe-sysroot" Without quotes, detection is as follows: Auto-detecting system features: ... dwarf: [ OFF ] ... dwarf_getlocations: [ OFF ] ... glibc: [ OFF ] ... gtk2: [ OFF ] ... libbfd: [ OFF ] ... libcap: [ OFF ] ... libelf: [ OFF ] ... libnuma: [ OFF ] ... numa_num_possible_cpus: [ OFF ] ... libperl: [ OFF ] ... libpython: [ OFF ] ... libcrypto: [ OFF ] ... libunwind: [ OFF ] ... libdw-dwarf-unwind: [ OFF ] ... zlib: [ OFF ] ... lzma: [ OFF ] ... get_cpuid: [ OFF ] ... bpf: [ OFF ] ... libaio: [ OFF ] ... libzstd: [ OFF ] ... disassembler-four-args: [ OFF ] Makefile.config:414: *** No gnu/libc-version.h found, please install glibc-dev[el].

Makefile.perf:230: recipe for target 'sub-make' failed make[1]: *** [sub-make] Error 2 Makefile:69: recipe for target 'all' failed make: *** [all] Error 2 With CC and CXX quoted, some of those features are now detected.
