>Description:
GCC 14 introduced a new build faiure on Solaris 11.4 host systems.

Solaris nm command does not generate the same output as the gnu nm command.

Do build.sh tools
>Fix:
Use the in-tree nm command:

 The proposed patch works corretly when building the sparc64 targe, but 
 has issues when building the sparc target.

 Will look into a solution that handles both sparc and sparc64 properly.

 can you arrange for it to use the /usr/xpg4/bin/nm?  i thought
 we knew how to do that for some things...

 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.
