[CT_NG] crosstool-ng 1.1.2 not support --enable-thread-safe at MPFR's configure processing.

[leemgs <leemgs at gmail dot com>]

When I used crosstool-ng ver 1.1.2(Release Date May-26,2008),
I failed because MPFR's configure is not support --enable-thread-safe.
So, I changed  thread-safe option from --enable-thread-safe to
--disable-thread-safe.
Why I do not use --enable-thread-safe option at MPFR's configure command?
