gcc-config: maintain ABI ordering for LDPATHv2.3.2

Before the change we ordered paths in reverse order
for both gcc versions and ABI lists:

    $ cat /etc/ld.so.conf.d/05gcc-x86_64-pc-linux-gnu.conf
    /usr/lib/gcc/x86_64-pc-linux-gnu/11.0.0/32
    /usr/lib/gcc/x86_64-pc-linux-gnu/11.0.0
    /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/32
    /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0

After the change we preserved ABI ordering
and use reverse gcc version ordering:

    $ cat /etc/ld.so.conf.d/05gcc-x86_64-pc-linux-gnu.conf
    /usr/lib/gcc/x86_64-pc-linux-gnu/11.0.0
    /usr/lib/gcc/x86_64-pc-linux-gnu/11.0.0/32
    /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0
    /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/32

In theory both should work. I practice some systems (like
riscv today) do not distinct between some ABIs. Let's
list valid ABI first to keep such systems running.
