[GIT PULL] bootconfig: Fixes for v7.3-rc7

[Google]

Hi Linus,

Bootconfig fixes for v7.3-rc7:

- bootconfig: give the footer size static_assert a message
   Add a message to static_assert() macro because it is required for
   the compiler before C23. This fixes a warning.

    bootconfig: give the footer size static_assert a message
    
    static_assert() without a message is a C23 feature, so clang warns:
    
      main.c:498:56: warning: '_Static_assert' with no message is a C23 extension [-Wc23-extensions]
    
    Add a message.
