Hello dear list,

I experimented (again) with moving a completed build of 12.4 64 bit to 
an older machine.
My build machine has an i7-6700, and I unpacked this to an older i5-3350 
after it successfully finished.
At first glance everything seemed to look fine until I tried to compile 
ethtool (to gain WOL capability).
The `configure`  script went through but while compiling the source I 
got an "illegal instruction" abort from gcc.
That was a bit surprising. I compiled the `gmp`  package as recommended 
with ` --host=none-linux-gnu`.
Looks like I have to recompile gcc too.

Stay healthy,
Thomas
