        src/sys/conf: Makefile.kern.inc

Log Message:
Switch from -std=gnu99 to -std=gnu11 by default.

This is needed for newer language syntax like u"foo" for UTF-16
string literals in UEFI.

As proposed on tech-kern:

https://mail-index.netbsd.org/tech-kern/2025/01/05/msg029919.html

Some commentators requested -std=c11 instead of -std=gnu11, but that
requires additional work -- some of it is a matter of providing asm
and typeof as aliases for __asm__ and __typeof__, but there's other
issues that need to be resolved too like PR toolchain/58969: use of
alloca is warning, not error, with -std=c11.  This is a smaller
incremental change.
