zig build: add --libc general option
This new option sets a default libc paths file to be used for all
LibExeObjSteps. Setting LibExeObjStep.libc_file overrides this default.
This is required to allow users to cross compile projects linking system
libraries without needing to patch the build.zig.2 files changed, 11 insertions(+), 0 deletions(-)
