Right - so I tried this as well and indeed I can confirm that it builds for me as
static. Atleast the build system doesn;t need changing as -sattic being propagated
to fianl link cmd.
There seems to be some weirdness with ARC tools: file reports
| ELF 32-bit LSB executable, *unknown arch 0xc3* version 1 (SYSV),
| dynamically linked, interpreter *empty*, for GNU/Linux 3.9.0, not stripped
That is clearly wrong !
And the static binary as expected doesn't seem to run on target - exits with -EACCESS.
