	Eliminate all GOT entries in the decompressor binary, by forcing hidden visibility for all symbol references, which informs the compiler that such references will be resolved at link time without the need for allocating GOT entries. To ensure that no GOT entries will creep back in, add an assertion to the decompressor linker script that will fire if the .got section has a non-zero size.

2020-02-23	efi/libstub: Use hidden visibility for all source files	Ard Biesheuvel
	Instead of setting the visibility pragma for a small set of symbol declarations that could result in absolute references that we cannot support in the stub, declare hidden visibility for all code in the EFI stub, which is more robust and future proof. To ensure that the #pragma is taken into account before any other includes are processed, put it in a header file of its own and include it via the compiler command line using the -include option.
