a348b4557d traceroute: properly reduce poll timeout 
This removes the problem where during the time we wait to declare
a target as unresponsive we receive an unrelated ICMP packet.
If there is enough traffic, this can make traceroute hang as
it never declares the target as unresponsive.

882062915d mount: for NFS use tcp per default rather than udp 
nfs-utils's mount.nfs uses TCP per default unless explicitly asked for
otherwise. This is also the expected behaviour for NFSv4, so ok there,
too.

91b77c3953 Compile options: default to -O2 when -Os is not available 
Recent versions of GCC for PowerPC systems suffer from some compiler
bugs which prevent the use of "--enable-target-optspace" in their
configuration, which makes the compiler option "-Os" unavailable;
for reference see

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48278
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45053

In the result, BusyBox will be compiled without any optimization
options, which causes a huge binary (1.8 MiB for default configuration
on PPC, built with gcc 54.51 from the Yocto / Poky / OpenEmbedded tool
chains).  This commit changes behaviour so "-O2" gets used as fallback
when "-Os" is not available.  This reduces the image size in above
test to 1.3 MiB.  This is still 10...15% more then what we get with
"-Os", but much better than using no optimization at all.
