    Link liblto_plugin with -liberty (gcc)

    GCC passes liblto_plugin.so in the linker invocation (part of "gcc -v file.c"):

    ld -plugin /usr/libexec/liblto_plugin.so -plugin-opt=/usr/libexec/lto-wrapper \
    -plugin-opt=-fresolution=/var/tmp//ccxda9Ar.res \
    -plugin-opt=-pass-through=-lgcc_s -plugin-opt=-pass-through=-lgcc \
    -plugin-opt=-pass-through=-lc -plugin-opt=-pass-through=-lgcc_s \
    -plugin-opt=-pass-through=-lgcc --eh-frame-hdr -dc -dp -e _start \
    -dynamic-linker /usr/libexec/ld.elf_so /usr/lib/crt0.o /usr/lib/crti.o \
    /usr/lib/crtbegin.o /var/tmp//cc7A7mOK.o --as-needed -lgcc_s --no-as-needed \
    -lgcc -lc --as-needed -lgcc_s --no-as-needed -lgcc /usr/lib/crtend.o \
    /usr/lib/crtn.o

    When attempting to use GNU GOLD, liblto_plugin.so cannot be used because it \
    has missing symbol xstrerror:

    ld: error: /usr/libexec/liblto_plugin.so: could not load plugin library: \
    /usr/libexec/liblto_plugin.so: Undefined PLT symbol "xstrerror" (symnum = 38)

    From Makefiles and sources inspection, liblto_plugin.so shall be linked with \
    libiberty (-liberty), a utility GNU library for internal usage with helping \
    functions.
