libcxxrt: don't export nonexistant symbols
Remove version entries that we don't build.
Add an arm specific Version.map and for other targets run the files
through sed to handle int vs long in new and delete.
Ideally we'd use the SYMBOL_MAPS functionality to preprocess with cpp,
but it doesn't currently handle C++ symbols so be annoyingly duplicative
for now.

they aren't present. Perhaps they should be static.

kboot: hostfs -- check for llseek failure correctly
The host_* syscalls are all raw Linux system calls, not the POSIX
wrappers that glibc / musl create. So we have to ranage change the
return value of host_llseek correctly to use the negative value hack
that all Linux system calls use.
This fixes a false positive error detection when we do something like
lseek(fd, 0xf1234567, ...); This returns 0xf1234567, which is a negative
value which used to trigger the error path. Instead, we check using the
is_linux_error() and store the return value in a long. Translate that
errno to a host errno and set the global errno to that and return
-1. lseek can't otherwise return a negative number, since it's the
offset after seeking into the file, which by definition is positive.
This kept the 'read the UEFI memory map out of physical memory' from
working on aarch64 (whose boot loader falls back to reading it since
there are restrictive kernel options that can also prevent it), since
the physical address the memory map was at on my platform was like

kboot: Create function for error checking.
Linux has the convention of returning -ERRNO to flag errors from its
system calls. Sometimes other negative values are returned that are
success... However, only values -1 to -4096 (inclusive) are really
errors. The rest are either truncated values that only look negative (so
use long instead of int), or are things like addresses or legal unsigned
file offsets or similar that are successful returns. Filter out the
latter.
