The new configure change between topevel and gas/ld is inconsistent.
Toplevel configure has

--enable-compressed-debug-sections={all,gas,gold,ld,none}

and gas/ld has --enable-compressed-debug-sections.  Toplevel
configure should take

--enable-compressed-debug-sections=all
--enable-compressed-debug-sections=gas
--enable-compressed-debug-sections=gold
--enable-compressed-debug-sections=ld
--enable-compressed-debug-sections=ld,gold
--enable-compressed-debug-sections=ld,gas

What should --enable-compressed-debug-sections without list do
at toplevel?
