Running the command manually with strace reveals that gcc is calling "gcc/as",
which is looking for a previous cross compiling version of "as". There is no
"as" built yet as far as I can see (No other "as", no "xas" no "arm-as"), and I
do not have an older cross compiler installed.
Changing as to be not executable makes gcc call "as" from the build system.
This fails, I believe it wants a cross compiler version.
I am unsure as to why "as" has not been built, would it be built later in the
process, or has it failed silently?
Cheers
