There is some disagreement between the compiler and the assembler as to
which instructions are supported.  As far as I can see, the power6
should support the fsqrt instruction.  So either the assembler
disagrees, or gcc is not correctly telling the assembler that it is
assembling power6 code.  You may need to get a newer assembler.
