toolchain@gentoo.org Gentoo Toolchain Project Enable Intel Control-flow Enforcement Technology (needs binutils 2.29 and gcc 8) Enable the new clone3 syscall within glibc. Can be disabled to allow compatibility with older Electron applications. build *all* locales in src_install; this is generally meant for stage building only as it ignores /etc/locale.gen file and can be pretty slow build and install libcrypt and crypt.h When USE=hardened, allow fortify/stack violations to dump core (SIGABRT) and not kill self (SIGKILL) build memusage and memusagestat tools enable optimizations for multiple CPU architectures (detected at runtime) Provide prebuilt libgcc.a and crt files if missing. Only needed for ABI switch. Build, and enable support for, the Name Service Cache Daemon protect stack of glibc internals Enable static PIE support (runtime files for -static-pie gcc option). Make internal pt_chown helper setuid -- not needed if using Linux and have /dev/pts mounted with gid=5 enable systemtap static probe points cpe:/a:gnu:glibc
