Tuomas Tynkkynen be2a2db0f1 grub2: Workaround flex bug
I think the flex update in 6bded45883
causes this failure, presumably due to upstream breakage:

````

Work around it for now.

description = "GNU GRUB, the Grand Unified Boot Loader (2.x beta)";
longDescription =
'' GNU GRUB is a Multiboot boot loader. It was derived from GRUB, GRand
Unified Bootloader, which was originally designed and implemented by
Erich Stefan Boleyn.
Briefly, the boot loader is the first software program that runs when a
computer starts. It is responsible for loading and transferring
control to the operating system kernel software (such as the Hurd or
the Linux). The kernel, in turn, initializes the rest of the
operating system (e.g., GNU).
