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.
