#   Currently builds with gcc 3.3 for i386, arm, mips, mipsel.
#   Only tested with multilib enabled.
#   For i386, long double is the same as double (64 bits).  While this
#      is unusual for x86, it seemed the best approach considering the
#      limitations in the gcc floating point emulation library.
#   For arm, soft float uses the usual libfloat routines.
#   The uClibc built will support _only_ applications compiled with the
#      -msoft-float flag.  To avoid CFLAGS problems, you may want to use
#      scripts similar to those in the build*/staging_dir/bin directory.
