It turns out that reverting the fix introduced in toolchain/58437 
(addition of NM to MAKE_ARGS) fixes the new problem after gcc14 was 
enabled.

Now the correct version of nm (/usr/bin/xpg4/nm) is picked up properly.

With the following patch at least sparc, sparc64, riscv32 and riscv64 
builds fine on a Solaris 11.4 system.
