The sandbox is built with the SDL2 library with invokes the X11 library which in turn calls getc(). But getc() in glibc is defined as

int getc(FILE *)

This does not match our definition.

int getc(void)

The sandbox crashes when called with parameter -l.

Rename our library symbol to be called _u_boot_getc(). To keep the coding changes minimal use a define on the sandbox only.
