description:
sysutils/grub2: Fix lex issues

Apparently depending on the compiler and version of lex used, one could
encounter two lex problems:

1) 'yy_fatal_error' defined but not used
2) 'yy_scan_bytes' compares signed and unsigned (char and int)

This patch resolves the problem.
sysutils/grub2 currently has no support for DragonFly, and there is
significant divergence from FreeBSD.  It will require some tested
patches to hostdisk.c and getroot.c at least.
