[RS6000] rs6000_linux64_override_options fix

Browse Source 
Commit c6be439b37 wrongly left a block of code inside an "else" block,
which changed the default for power10 TARGET_NO_FP_IN_TOC
accidentally.  We don't want FP constants in the TOC when
-mcmodel=medium can address them just as efficiently outside the TOC.

	* config/rs6000/rs6000.c (rs6000_linux64_override_options):
	Formatting.  Correct setting of TARGET_NO_FP_IN_TOC and
	TARGET_NO_SUM_IN_TOC.
