6<para>This package is known to behave badly when you have changed its default
7optimization flags (including the -march and -mcpu options). Therefore, if you
8have defined any environment variables that override default optimizations,
9such as CFLAGS and CXXFLAGS, we recommend unsetting them when building
10Grub.</para>
