xtensa: Makefile: cleanup

Browse source 
Some options which are already defined by the build system
for the C compiler or assembler have been removed: -c,
-xassembler-with-cpp, -nostdinc.
References to deleted variable flagALongCall and flagLongCall
removed.
Formatting for 80 columns, there is now one flag per line.
