sim: drop --enable-sim-cflags option

No other sub directory provides such a configuration option, so
drop it from the sim dir as well.  This cleans up a good bit of
code in the process.

If people want to use custom flags for just the sim, they can
still run configure+make by hand in the sim subdir and use the
normal CFLAGS settings.

-Specify additional C compiler flags that are to be used when compiling

-PSIM places heavy demands on both the host machine and its C compiler.  So that
-the builder has better control over the compiler the above option can be used
-to pass additional options to the compiler while PSIM is being built.
-
-Ex: No debug information
-
-PSIM can be built with everything inline.  Unfortunately, because of
-all the debugging information generated the C compiler can grow very
-very large as a result.  For GCC, the debug information can be
-restricted with the `-g0' option.  To specify that this option should
-be include in the CFLAGS when compiling the psim source code use:
-
-	--enable-sim-cflags=-g0
-
-Ex: Additional optimization flags
-
-A significant gain in performance can be achieved by tuning the
-optimization flags passed to the C compiler.  For instance on an x86
-you may consider:
-
-	--enable-sim-cflags='-g0 -O2 -fno-strength-reduce -f...'
