[arch-general] virtual memory exhausted

[Jorge Almeida]

I'm not sure this is an Arch issue, but I can't figure out what else can be.

I'm trying to compile non-Arch stuff in an arch host. I tried Binutils
(of LFS) and Buildroot (of uclibc). Both failed with the "virtual
memory exhausted: Cannot allocate memory" error.
The computer is a one-user workstation, which wasn't doing anything
else worth mentioning...
I tried both as root and as  common user, same problem...

Maybe there is some arch-specific configuring to do? I have no idea
whether these limit parameters require tweaking...
