Tune for new MacOS toolchains
* Doesn't seem to like nocombreloc
* i686 doesn't have the efi-app-ia32 target (bug in binutils??)
* Set float manually on ARM32 due to generic toolchain
* Ensure _DYNAMIC symbol exists

0bb329b0bf Merge .plt into .text
ld writes .plt immediately after .text

0f9c15fe4f riscv: Update SPDX license identifiers
The whole gnu-efi project is licensed under BSD license, see [1].
However some of the RISC-V codes have conflict license identifiers:

- Some mention GPL-2.0+ in the SPDX license part, but the long license
  header indicates it's actually BSD and GPL-2.0+ dual-licensed
- Some mention GPL-2.0+ in the SPDX license part only
- Some do not have any license indication

To have a matching license with the whole project, this commit updates
all RISC-V codes to have the correct SPDX license identifiers
(GPL-2.0+ or BSD dual-license).

15f10734e7 Add some COMDAT sections
When using function/data sections option from
gcc, some additional un-packed sections get created
move these to there correct placement if not already
included

sections seen on x86/x86_64/aarch64:
.gcc_except_table.efi_main
.bss.debugging

.gcc_except_table.* only appears on objcopy archs

98f1250742 riscv: Fix ld RWX warning
The current ld script places .dynamic section right after .text, which
results in that one LOAD segment contains both data and code. Binutils
2.39 and later will throw a warning if RWX segments exist. Code and
data should be placed in different LOAD segments with different
permissions. This patch adds a gap between data and code sections which
is taken from the default ld script in riscv64.
