• abi_mips_n32 - 64-bit (32-bit pointer) libraries
• abi_mips_n64 - 64-bit libraries
• abi_mips_o32 - 32-bit libraries
• abi_s390_32 - 32-bit (s390) libraries
• abi_s390_64 - 64-bit (s390x) libraries
• abi_x86_32 - 32-bit (x86) libraries
• abi_x86_64 - 64-bit (amd64) libraries
• abi_x86_x32 - x32 ABI libraries
• alsa - Add support for media-libs/alsa-lib (Advanced Linux Sound Architecture)
• coreaudio - Build the CoreAudio driver on Mac OS X systems
• cpu_flags_ppc_altivec - Use the AltiVec/VMX instruction set
• cpu_flags_x86_3dnow - Use the 3DNow! instruction set
• cpu_flags_x86_sse - Use the SSE instruction set
• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
