PR/48172: Reinhard Speyerer: u3g(4): add 4G Systems XS Stick W14 support
regen
Missing alias for strerror_l.
Preserve -std=* options as they may change the dependency list.
KNF multi-line comments.
Use C99 designated initializers.
Update LLVM/Clang snapshot to r189662. This includes many improvements
to the new SLP vectorizer, fast codegen support for PPC and using
terminfo for the color sequences. In addition, add (optional) build
infrastructure for lld to allow easier testing. This is controlled by
MKLLD.
Use C99 designated initializers.
Do not apply shellErrFlag unless errCheck is true.
Use less got, add END(), make thumb tolerant.
Add the FS_SUJ flag for journaled softupdates from FreeBSD.

This conflicts with our flag for FS_INDEXDIRS. Apparently FreeBSD
changed that arbitrarily on their end when implementing journaled
softupdates, so follow their lead.

Unfortunately, the new value they use for FS_INDEXDIRS conflicts with
our flag FS_DOQUOTA2 for 64-bit quotas. Since the only thing in our
tree that knows about FS_INDEXDIRS is dumpfs (for printing it), leave
FS_INDEXDIRS commented out.

Also add FS_NFS4ACLS from FreeBSD, commented out because it conflicts
with our FS_DOWAPBL, and FS_TRIM.

(We could honor FS_TRIM as we have code for doing that; however I'm
not sure why FreeBSD chose to make it an on-disk flag instead of e.g.
a mount option and it seems problematic to me. In any case, not in
this commit.)

Also see a post I just made in tech-kern about the flag conflicts.
Teach this to print FS_SUJ (and FS_GJOURNAL, whatever that is, as it
was missing for some reason) and cope with FS_INDEXDIRS not currently
being defined.

Since FS_SUJ actually appears in the wild, it's fairly important to
recognize it.
Print FS_TRIM too.
Prelimary config goo for CubieBoard 1 & 2
(config is happy with it)
print an error if we failed to allocate.
Fix debug build by adding cgram.debug.
Use CPPFLAGS.src and not COPTS.src to override -std=c++11 flag. The
latter doesn't help make depend.
no EFR on tl16c750, use AFE bit on MCR reg instead for flow control
