I merged your commit for ANSI function definition for newflist() in kconfig. Thanks for your help and involvement in DiscoBSD. |

Hi Chris, thanks for your merge. Sorry for the silence, I've been very busy the last few weeks/months. I'll have more time in the next few weeks, I will review all that. |

Build the stm32 kernels with -fcommon added to CMACHFLAGS and
-nopie removed from LDFLAGS in Makefile.kconf.
Regenerate stm32 kernel Makefiles.
-nopie (and/or -no-pie or the many other variations) is the
default for arm-none-eabi-{gcc,ld}, so removing it does not
change the produced kernel binary.
Prior to GCC 10 -fcommon was the default. GCC 10+ defaults to
-fno-common. Use -fcommon until the kernel is -fno-common clean.
See https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=6271dd984d7f92
This commit does not change the produced kernel binary with:
- OpenBSD/amd64 6.8 and 7.3, with arm-none-eabi-gcc-linaro 7.4.1.
- Ubuntu/amd64 18.04 LTS, with gcc-arm-none-eabi 7.3.1.
This commit fixes "-nopie not an option" errors and "multiple
definition of" errors with:
- FreeBSD/amd64 13.2, with both arm-none-eabi-gcc 11.3.0 and
gcc-arm-embedded 10.3.1.
- Ubuntu/amd64 23.04, with gcc-arm-none-eabi 12.2.1.
Modern FreeBSD and Ubuntu are now able to build stm32 kernels.
This commit is inspired/based on previous work by @lhondareyte in
pull request #2 and @saper in issue #4, and the -fno-common work
done in OpenBSD for base clang/llvm.

Update the char version[] in vers.c, generated by the shell script sys/conf/newvers.sh, for the DiscoBSD operating system. The old char version[] string stated, for stm32, something like: 2.11 BSD UNIX for STM32, rev G469 #1: Thu Jan 18 08:51:11 MST 2024 chris@stm32.discobsd.org:/sys/stm32/f412gdisco The new char version[] string states, for all architectures: DiscoBSD 2.1 (F412GDISCO) #2 473: Fri Jan 19 00:52:08 MST 2024 chris@stm32.discobsd.org:/sys/stm32/f412gdisco The top line information values, from left to right, are: ostype, osrelease, kernel id, compile version, git repo number, date. The top line is used by motd to be displayed upon each log in. Other simple cleanups to the file for regularity.
