examples: api: allow build with private libgcc

Nevertheless, this patch has to also touch the top-level Makefile to fix
this problem because the current top-level Makefile does not specify
libgcc as a prerequisite of examples/api, and explicitly builds
examples/api _before_ libgcc.
For testing this patch, I added the following to configs/seaboard.h and
ran demo.bin on a Seaboard.

accessed from plain memory or the IO region. However the error
path checks whether IO region was obtained - twice. Fix up the

ftgmac100: reset fix when supports wake on lan
This patch move the reset function from initialization to
driver register procedure.
Some embedded system supports wake on lan nowadays. On this kind of system,
the ftgmac100 will be still supplied power after the system has been
shut-down by Linux. Hence the register used by linux won't be clear
when the system has been powered-off.
The origin ftgmac100 driver in u-boot will only register
driver and functions to network stack and won't reset the ftgmac100
hardware if the network won't be used during boot-up.
This will lead ftgmac100 continue receiving packets and then might corrupt
linux kernel when booting up.
So we reorder the hardware reset function earlier to force the hardware
to be reset whether it will be used or not.

Move timestamp and version files into 'generated' subdir
There is a rather subtle build problem where the build time stamp is not
updated for out-of-tree builds if there exists an in-tree build which
has a valid timestamp file. So if you do an in-tree build, then an
out-of-tree build your timestamp will not change.
The correct timestamp_autogenerated.h lives in the object tree, but it
is not always found there. The source still lives in the source tree and
when compiling version.h, it includes timestamp_autogenerated.h. Since
the current directory is always searched first, this will come from the
source tree rather than the object tree if it exists there. This affects
dependency generation also, which means that common/cmd_version.o will not
even be rebuilt if you have ever done an in-tree build.
A similar problem exists with the version file.
This change moves both files into the 'generated' subdir, which is already
used for asm-offsets.h. Then timestamp.h and version.h are updated to
include the files from there.
There are other places where these generated files are included, but I
cannot see why these don't just use the timestamp.h and version.h headers.
So this change also tidies that up.
I have tested this with in- and out-of-tree builds, but not SPL. I have
looked at various other options for fixing this, including sed on the dep
files, -I- and -include flags to gcc, but I don't think they can be made
to work. Comments welcome.

zlib: handle overflow while calculating available stream input size
If compressed data is located in sectors at the end of the flash and
it's offset + input stream size > 0xFFFFFFFF, the uncompressing time
is very long, since processing of the stream is done bytewise (and
not blockwise) due to overflow in inflate_fast() while calculation
and checking for enough input available.
Check for this overflow condition and limit the available stream
input size to the actually max. possible input size. This fixes
the problem.
The issue is easily reproduceable by placing a gziped bitmap in flash,
e.g. at FFF80000, and running 'bmp' commands like 'bmp info FFF80000'
or 'bmp display FFF80000'. The uncompressing can take up to 3 sec.
whereas it should normaly take a fraction of a second. If the
