od_bloaty: fix floating point output
Currently od_bloaty does this:
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -f
od: invalid character 'F' in type string 'fF'
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t fD
od: invalid character 'D' in type string 'fD'

0000000
0000010
The first two occur because the alphabetic length specifier isn't being
properly skipped. The third is due to the empty length specifier being
treated as alphabetic so we fall off the end of the FDL_sizeof array with
undetermined consequences. Coreutils defaults to printing a double in
this case.
With this patch the output is:
$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -f
0000000 0.
0000000e+00 0.

$ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t fD

printf: fix format string sanity check
One of the tests for printf checks for an invalid bare '%' in the
format string:
$ busybox printf '%' a b c
printf: %: invalid format
On x86_64 a slightly different test doesn't work correctly:
$ busybox printf '%' d e f
printf: invalid number 'd'
printf: invalid number 'e'
printf: invalid number 'f'
On other platforms the test fails randomly depending on how the
arguments are laid out in memory.
There are two places in the code where strchr is used to determine if
a character in the format string is valid. However, strchr also returns
a valid pointer if the character being searched for is the null terminator
thus causing the code to incorrectly suppose that a valid character has
been found.
Add explicit checks for the null terminator.

However, arch/$(ARCH)/Makefile gets included *after* Makefile.flags,

Fix this by including arch/$(ARCH)/Makefile *before* Makefile.flags.

libbb: do not die if setgid/setuid(real_id) on startup fails
Based on a patch from Steven McDonald <steven@steven-mcdonald.id.au>:
This makes 'unshare --user' work correctly in the case where the user's
shell is provided by busybox itself.
'unshare --user' creates a new user namespace without any uid mappings.
As a result, /bin/busybox is setuid nobody:nogroup within the
namespace, as that is the only user. However, since no uids are mapped,
attempting to call setgid/setuid fails, even though this would do
nothing:
$ unshare --user ./busybox.broken ash
ash: setgid: Invalid argument
'unshare --map-root-user' still works, but because Linux only allows
uid/gid mappings to be set up once, creating a root mapping makes such
a namespace useless for creating multi-user containers.
With this patch, setgid and setuid will not be called in the case where
they would do nothing, which is always the case inside a new user
namespace because all uids are effectively mapped to nobody:
$ id -u
1000
$ ls -lh busybox.fixed
-rwsr-xr-x 1 root root 826.2K May 21 00:33 busybox.fixed
$ unshare --user ./busybox.fixed ash
$ id -u

This came to light when I ran into a use-case where someone was selecting

Some watchdog implementations may do things other than issue
a reboot on a watchdog timeout. In this case, there's the
possibility of restarting this program from the state of
the watchdog device not being properly stopped (done by writing
a 'V' and closing the device). Since it wasn't stopped, the
driver may not be able to restart the watchdog when this program
reopens it and starts pinging it.
To fix this, the code will always first issue the stop when it
starts up.
