Jam comparison logic is string-based, and so was detecting GCC >= 10
as being < 2. This rectifies that by removing the GCC version parsing
from Jam logic entirely, and setting various BuildConfig variables
instead.

Since the boot ROM API structure is declared with a custom alignment, we
simulate it with padding bytes around, and use aligntest.prg to verify
using ARAnyM + TOS/MiNT as we know how to link simple PRG files.
It now prints something to the screen then panics when initializing the
heap.
For now one must insert the loader manually into an existing floppy

I am using this to use clang+lld for linking on ARM builds,
which seems to be more tolerant than binutils ld is, and
gets the build a bit farther for now.
It warns on snprintf's output "possibly" being truncated (e.g.,
two B_PATH_NAME_LENGTH chars being concatenated together) which may
be exactly the behavior the programmer wanted. So that's not very
helpful.
All of Barrett's individual reverts have been squashed into this
one commit, save a few actual bugfixes.

On x86 and x86_64, this warning is never emitted because it is perfectly
fine to do unaligned access. On sparc, such accesses are not supported
by the hardware and will generate a SIGBUS. This must be caught by a
trap handler, and the unaligned access performed there, slowly, using
byte by byte access.
However, making this a Werror is annoying because it will trigger
everytime one casts a byte pointer to something larger, even when
alignment is actually preserved. So, removing all such warnings would be
nearly impossible (for example, just for the mergesort function, there
is a whole GSoC project for it at FreeBSD).
Keep it as a warning for now. The warning can be silenced by using
BytePointer, if desired. We should also investigate where the SIGBUS
trap is triggered a lot and consider improving the alignment of data
where possible.

It warns when you try to use some standard library functions
without including the system headers, which we don't
care about as we are providing the system headers in the tree.
I added this here so that one could set -Wextra in BuildConfig and
not be bombarded with useless warnings; but it seems that GCC2 chokes
on it instead of ignoring it. Oh well.
* Move -fPIC to ccBaseFlags, as we don't want it in ASFLAGS.
* Remove -fPIC from BOOT_CCFLAGS, as we never want it in there.
* Move EFI flags to the actual EFI setup location.
Clang doesn't support -maccumulate-outgoing-args, -nostartfiles
is not needed in LDFLAGS (and lld doesn't know about it anyway),
and Clang uses .dynstr so we need to copy it also.
* I mean, qemu 3.0 supports it.
* Nobody get excited, we need all the triplets added to
our gcc buildtools. clang 7.0 seems to be cool with riscv though.
