rs6000: Adjust -mdejagnu-cpu to filter out -mtune [PR106345]
As PR106345 shows, when configuring compiler with an explicit
option --with-tune=<value>, it would cause some test cases to
fail if their test points are sensitive to tune setting, such
as: group_ending_nop, loop align etc. It doesn't help that
even to specify one explicit -mcpu=.
This patch is to adjust the behavior of -mdejagnu-cpu by
filtering out all -mcpu= and -mtune= options, then test cases
would use <cpu> as tune as the one specified by -mdejagnu-cpu.
