[PATCH 2/3] selftests/nolibc: ignore -Wmissing-prototypes
From: Thomas Weißschuh
Date: Thu Jan 23 2025 - 15:11:59 EST
To make sure nolibc itself is compatible with -Wmissing-prototypes the
compiler flag should be enabled when building nolibc-test.
However some of its functions are non-static to ease debugging [0],
triggering the compiler warning.
Disable the warning inside nolibc-test while still enabling it for
nolibc itself.

It's a bit iffy, but I only see three possibilities:
1) Make the functions static
2) Use #pragma
3) Add dummy prototypes
1) was NACK-ed before, so I used 2)
