Nested functions are not supported in C, but are permitted as an extension
in the GNU C dialect. Commit cb2f15c5448 ("normal/main: Search for specific
config files for netboot") added a nested function which caused the build
to break when compiling with clang.
Break that out into a static helper function to make the code portable again.
