[edk2-devel] [PATCH edk2-platforms 1/1] Silicon/SynQuacer: Fix CLANGDWARF build

[Ard Biesheuvel via groups.io]

From: Ard Biesheuvel <ardb@kernel.org>

Drop the CLANG3x build options, and add ones for CLANGDWARF so that
SynQuacer based platforms can be built with it.

Instead of copying the -no-integrated-as option that CLANG3x used, let's
fix the assembler code so it can be built with Clang's integrated
assembler. Also switch to LLD for linking the code, which is what
CLANGDWARF uses natively (and build hosts may lack a cross linker for
AArch64 when using CLANGDWARF)
