8bd5e2f15c stand/efi: Pass --no-dynamic-linker to ld.bfd >= 2.34.
ld.bfd in binutils 2.34+ now reports an error in more cases for custom
ldscripts that do not place PHDRs in a LOAD segment.  However, EFI
binaries are not dynamic binaries which need PHDRs, so pass
--no-dynamic-linker to disable this check.

5b13fa7987 ufs: Rework shortlink handling to avoid subobject overflows
Shortlinks occupy the space of both di_db and di_ib when used. However,
everywhere that wants to read or write a shortlink takes a pointer do
di_db and promptly runs off the end of it into di_ib. This is fine on
most architectures, if a little dodgy. However, on CHERI, the compiler
can optionally restrict the bounds on pointers to subobjects to just
that subobject, in order to mitigate intra-object buffer overflows, and
this is enabled in CheriBSD's pure-capability kernels.

Instead, clean this up by inserting a union such that a new di_shortlink
can be added with the right size and element type, avoiding the need to
cast and allowing the use of the DIP macro to access the field. This
also mirrors how the ext2fs code implements extents support, with the
exact same structure other than having a uint32_t i_data[] instead of a
char di_shortlink[].

c399283c71 Add an loader command on arm64 to sync the cache
On boot we don't need to perform any CPU cache management when the IDC
and DIC fields in the ctr_el0 register are set. Add a command to tell
loader to ignore these fields. This could be useful, for example, if the
hardware is misreporting the values and we are missing a quirk to enable
it.

It is not expected this will be needed, but is only intended as a
workaround to ensure the kernel can still boot.

c25d9aff46 loader: Add preload operation to fs_ops
When we load an ELF file (kernel or module) we do seek(2) a lot to
parse/load the different sections of the ELF file.
Protocol like TFTP suffers a lot from this as there is no resume or
a way to start the tranfer from a specified offset in the file.
fs_preload is added to help those protocol.
Call preload just after opening the ELF file that we need to load so
the underlying method can cache the hole file and then read/lseek operations
are faster.

o update version to 1.5 to reflect the new way of building

This results in a more consistent build system and should represent no
functional change, apart from powerpc version getting new help

BROKEN_OPTION instead of the incidental exclusion we had before due to
