Toolchain: Enable RELRO support for AArch64

Browse source 
The BFD linker requires the `COMMONPAGESIZE` emulation parameter to be
set in order to enable RELRO support for AArch64. As we are adding a
custom `emulparams` file anyways, let's also tell LD that our ELF
interpreter is called `/usr/lib/Loader.so`.

This commit also removes some vestigial references to i686 SerenityOS.
The one in `gas/configure.tgt` is still needed, as it also handles
x86_64.

@ -6,3 +6,11 @@ Add support for SerenityOS
Teaches the assembler, BFD, and the linker about the SerenityOS target
triple.
We set '/' to not start a comment in GAS, as the QEMU port uses it for
division in constant expressions in assembly files (cf. as --divide).
`/usr/lib/Loader.so` is set as the default ELF interpreter.
On AArch64, we set `COMMONPAGESIZE` to enable RELRO support.
