Add --enable-compressed-debug-sections={all,gas,gold,ld}

This patch removes the gas configure option:

--enable-compressed-debug-sections

and adds a toplevel configure option:

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

to enable compressed debug sections for gas, gold or ld by default.  At
the moment, this configure option is ignored by gold and ld.  For x86
Linux targets, default to compressing debug sections in gas.

	Sync with binutils-gdb:
	PR gas/19109
	* configure.ac: Add
	--enable-compressed-debug-sections={all,gas,gold,ld}.
	* configure: Regenerated.
