[PULL 03/14] tests/tcg: Use --noexecstack with assembler files


From: Alex Bennée
Subject: [PULL 03/14] tests/tcg: Use --noexecstack with assembler files
Date: Tue, 30 Jul 2024 17:22:26 +0100

From: Richard Henderson <richard.henderson@linaro.org>

Add the --noexecstack assembler command-line option to avoid:

  /usr/bin/ld: warning: boot.o: missing .note.GNU-stack section implies 
executable stack
  /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a 
future version of the linker

which is enabled by default with current debian cross toolchains.
