Re: netbsd-10, merging device-streams (xstreamtodev, rdbinfo)

Hi,

I went ahead and tried building the toolchain from
https://github.com/bebbo/amiga-gcc with netbsd-9.3, amd64.

The GNU Makefile does something like this (de-makified):
gcc .repos | sed -e 's/[[:blank:]]\+/ /g' |cut -d' ' -f2

To extract fields from that file, which is copied there from
default-repos earlier in the Makefile.

This file happens to mix spaces and tabs, and use multiple spaces in a
row. GNU cut behaviour is different from netbsd, as GNU seems to treat
multiple spaces as one space, and tabs as one space as well.

After editing default-repos to deal with this, it can start building.
It'll get as far as this:

/home/rvalles/work/amiga-gcc/projects/binutils/bfd/amigaos.c:4031:37:

       ^~~~~~
gmake[4]: *** [Makefile:1761: aout-amiga.lo] Error 1

This is likely to do with our host gcc being older than expected.
