Following the conversion of the SPDX license tags, a number of files compiled with -pedantic now generate warnings similar to the following for using C99-style '//' comments in ISO C90 code:
tools/gen_eth_addr.c:1:1: warning: C++ style comments are not allowed in ISO C90 // SPDX-License-Identifier: GPL-2.0+ ^
The SPDX comment-style change means that these files have adopted C99, so need to change the language-standard to --std=gnu99 or --std=gnu11 to let the compiler know this.
As we now require GCC 6 or newer for the cross-compiler, the project has implicitly moved the project to GNU11: let older GCC versions on various Linux distros know to treat our host tools as GNU11 as well.
