If nocrt is true, then the compilation for cc_shared_library, cc_binary (shared or static binaries) will _not_ link against their respective crtbegin and crtend libraries. nocrt is true only for the Bionic libraries themselves. For everything else that links against the Bionic runtime, crtbegin and crtend libraries are used. This makes the "nocrt: false" case the majority. Hence, if nocrt is explicitly false, we omit the generating attribute in bp2build. If nocrt is explicitly true (link_crt is false), the Starlark macro will disable the link_crt cc_toolchain feature.
