Some architectures need to set options in the file configparms.
This is the case for sh3/4, which really need to set configparms
to "no-z-defs=yes" as of gcc-3.4/glibc-2.3.2.
Unless you are building a toolchain for sh3/4, you should leave that empty.
Note: this is awkward, and doesn't work well if you need more than one
