USE flags

• 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
• acl - Add support for Access Control Lists
• blake2 - Enable Blake2 hash support via app-crypt/libb2.
• bzip2 - Allow accessing bzip2-compressed archives through libbz2 (which comes with app-arch/bzip2). This only affects libarchive's native support: bsdtar will keep using bunzip2 as a filter if that's not built-in.
• e2fsprogs - Use file flags from sys-fs/e2fsprogs headers instead of virtual/os-headers headers
• expat - Enable the use of dev-libs/expat for XML parsing
• iconv - Enable support for the iconv character set conversion library
• lz4 - Enable support for lz4 compression (as implemented in app-arch/lz4)

• lzo - Enable support for lzo compression
• nettle - Use dev-libs/nettle as crypto backend
• static-libs - Build static versions of dynamic libraries as well
• verify-sig - Verify upstream signatures on distfiles
• xattr - Add support for extended attributes (filesystem-stored metadata)
• zstd - Enable support for ZSTD compression
