my CC is clang and my LD is ld.lld, emerge --info says: Portage 2.3.103 (python 3.7.7-final-0, default/linux/amd64/17.1, gcc-10.1.0, glibc-2.31-r5, 5.4.0-1015-aws x86_64) ld GNU ld (Gentoo 2.34 p4) 2.34.0
${LD} is rarely used. For most packages, linker is called through compiler and selected by -fuse-ld=... in ${LDFLAGS}. Information about active version of gcc and binutils is still useful. It could be shown using some special formatting in list of packages shown slightly below in output of `emerge --info`. Example with << >> around versions: sys-devel/autoconf: 2.13-r1::gentoo, 2.69-r5::gentoo sys-devel/automake: 1.16.2::gentoo sys-devel/binutils: 2.33.1-r1::gentoo, <<2.34-r1::gentoo>> sys-devel/gcc: 8.4.0-r1::gentoo, <<9.3.0-r1::gentoo>>, 10.1.0-r1::gentoo It should not be only colors, because colors would be lost when users copy output to bugzilla. After above change is implemented, gcc version in first line could be dropped. Line starting with "ld " is actually for /usr/bin/ld, not ${LD}. Information about version in this line would be redundant, but information about BFD linker versus GOLD linker could be still useful. (sys-devel/binutils has "default-gold" USE flag, which affects /usr/bin/ld.) (For ${CC}, ${LD} etc., see bug #722456.) (For LLVM toolchain, see bug #730152.)
Maybe `ld --version` can be parsed, and information about linker shown as one of the following /usr/bin/ld: BFD /usr/bin/ld: GOLD /usr/bin/ld: LLD
