Since https://github.com/gentoo/gentoo/commit/ef894cec8dee3758cfde620b87d10b2774419cdf , running meson configured for cross-compiling will use CFLAGS on the native host compiler, which prevents it from running. Reproducible: Always Steps to Reproduce: 1. emerge -v xorg-proto # with a cross-compiling profile using -mcpu etc. Actual Results: The Meson build system Version: 0.52.1 Source dir: /var/tmp/portage/x11-libs/libxkbcommon-0.10.0/work/libxkbcommon-0.10.0 Build dir: /var/tmp/portage/x11-libs/libxkbcommon-0.10.0/work/libxkbcommon-0.10.0-.arm Build type: cross build Project name: libxkbcommon Project version: 0.10.0 Appending CFLAGS from environment: '-O2 -pipe -ggdb -flto=jobserver -march=armv7ve+simd -mtune=cortex-a17 -mfpu=neon-vfpv4 -ftree-vectorize' Appending LDFLAGS from environment: ['-Wl,-O1', '-Wl,--as-needed'] meson.build:1:0: ERROR: Compiler x86_64-pc-linux-gnu-gcc can not compile programs. Expected Results: It should build and install properly like it did a day ago.
