(https://sourceware.org/pipermail/binutils/2022-August/122246.html):

> The ELF linker will now generate a warning message if the stack is made executable.

Let's suppress the warnings in assembly files by adding non-executables
stack markings. This fixes at least systemd build which uses '-Wl,--fatal-warnings':

Add support for LoongArch64 architecture

riscv64: finalize efibind.h

There's little reason not to derive the RISCV64 version of efibind.h
from the AARCH64 version, especially as the current version is missing
required macros such as EFI_DRIVER_ENTRY_POINT() which breaks the
compilation of some drivers.

The only major difference we introduce from AARCH64 is to consider
that any toolchain that supports RISCV64 is modern enough to support
<stdint.h>. Also, as we preserve the added definition for BOOLEAN,
we guard it with an ifndef in anticipation of MSVC RISCV64 support.

We validated these changes by confirming that they now allow gnu-efi
to be used to compile a set of UEFI drivers for RISCV64.

Set NumberOfSymbols to zero

Acoording to what the spec says about the number of sybols [1]:

"This value should be zero for an image because COFF debugging
information is deprecated."

Changing as if not zero it causes problems to llvm-objcopy. This
affects only the architectures where COFF is not supported by objcopy
and where we build the PE header via assembly code.

ARM: hide 'hidden' pragma for hosted build

The hidden visibility #pragma in inc/arm/efibind.h was meant to inform
the compiler that symbols with external linkage are never exported from
shared libraries [and thus never preempted] when executing in UEFI context
(since UEFI does not support shared libraries). This allows the compiler to
generate relative symbol references instead of GOT entries, which is much more
efficient since the latter need to be relocated before invoking the entry
point of the UEFI app.

However, as it turns out, this pragma is leaking into other code that does
not run in UEFI context, but simply needs to access data structures that
UEFI defines. So make the pragma dependent on whether we are building with
-ffreestanding, which is only used for bare metal code such as UEFI.
