Most compiler toolchains and tools have support for PREFIX environment
variables to specify their location, but Apple mtoc does not. While
it used to be in a stable install location, it has recently been
deprecated and ocmtoc is maintained as a fork. Homebrew has accepted
ocmtoc into its repository, including its ARM version. As Homebrew on
ARM does not install its packages into /usr/local, XCODE5 currently
does not work on Apple silicon with ocmtoc installed via Homebrew.
Introduce the MTOC_PREFIX environment variable to customize the
installation location of Apple mtoc or ocmtoc.

For now "-read_only_relocs suppress" is safe, as relocations can now
target __TEXT without triggering the issue with Mach-O relocation
offsets

Commit c25d390 disabled PIE generation for GCC49 and GCC5 as the GCC toolchains
at the time started enabling it by default. LLVM 15 has now done the same thing
for all Linux targets [1]. This causes the emission of a GOT with relocations
that GenFw does not currently support.
As such, disable PIC and PIE for the CLANGDWARF toolchain for IA32 targets, as
already done for GCC49 and GCC5, to support LLVM 15.

UefiCpuPkg modules like ExceptionHandlerAsm.nasm require relocations
to .text or PIC as they use instructions like mov or bt against
external symbols:
1. mov rax, ASM_PFX(CommonInterruptEntry)
2. mov rax, HookAfterStubHeaderEnd
3. bt [ASM_PFX(mErrorCodeFlag)], ecx
4. mov [rcx + (@VectorNum - HookAfterStubHeaderBegin)], al
It is not easily possible to rewrite 3/4 cases without involving
more registers or more commands, and EDK II has never targeted
read-only .text at load time, only at runtime.
Change the defaults to let OVMF compile by CLANGDWARF as per:

Fix gcc: warning:
-x c after last input file has no effect
These kind of flag can only affect the source code after them.
For the build command in build_rule.template, we have no other source code or object after these two flag.
It seems we don't need them here.

This reverts commit ff36b2550f94dc5fac838cf298ae5a23cfddf204.
Has no effect because GCC_IA32_CC_FLAGS and GCC_X64_CC_FLAGS are unused.

The ebp/rbp register can either be used for the frame pointer or
as general purpose register. With gcc (and clang) this depends
on the -f(no-)omit-frame-pointer switch.
This patch updates tools_def.template to explicitly set the compiler
option and also add a define to allow conditionally compile code.
The new define is used to fix stack switching in TemporaryRamMigration.
The ebp/rbp must not be touched when the compiler can use it as general
purpose register. With version 12 gcc starts actually using the
register, so changing it leads to firmware crashes in some
configurations.

Building with the CLANG35 and CLANG38 toolset fails because of variables
which are set but not otherwise used in the RELEASE build.
GCC added -Wno-unused-but-set-variable back in 2016, and later added
-Wno-unused-const-variable. Add those to CLANG35_WARNING_OVERRIDES and
CLANG38_WARNING_OVERRIDES.

New macro OBJCOPY_STRIPFLAG is added in build_rule.template to replace
'--strip-unneeded -R .eh_frame', so that module can have some unique
objcopy flags for its own purpose.
In tools_def.template, set '--strip-unneeded -R .eh_frame' as default
value of OBJCOPY_STRIPFLAG.
