Subject: [PATCH 01/12] qemu: Add addition environment space to boot loader
 qemu-system-mips

Upstream-Status: Inappropriate - OE uses deep paths

If you create a project with very long directory names like 128 characters
deep and use NFS, the kernel arguments will be truncated. The kernel will
accept longer strings such as 1024 bytes, but the qemu boot loader defaulted
to only 256 bytes. This patch expands the limit.
