PATCH: doc/install.texi (*-*-freebsd*)

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

Documentation change tested by running install.texi2html and
inspecting the output HTML in a browser.  Installed on mainline since
it matches the new reality for the target.

	* doc/install.texi (*-*-freebsd*): Update.

! In principle, @option{--enable-threads} is now compatible with
! @option{--enable-libgcj} on FreeBSD@.  However, it has only been built
! and tested on i386-*-freebsd4.5 and alpha-*-freebsd5.0 and important
! test suite failures remain.  Multi-threaded boehm-gc (required for
! libjava) exposes severe threaded signal-handling bugs on FreeBSD before
! 4.5-RELEASE.  The alpha port may not fully bootstrap without some manual
! intervention: gcjh will crash with a floating-point exception while
! generating @file{java/lang/Double.h} (just copy the version built on
! i386-*-freebsd* and rerun the top-level gmake with no arguments and it
! should properly complete the bootstrap).  Other CPU architectures
! supported by FreeBSD will require additional configuration tuning in, at
! the very least, both boehm-gc and libffi.
