If you wish to use non-default GCC flags when compiling the stage2 and

tested here than the default of @samp{-g -O2}, but should still work.

Note that using non-standard @code{CFLAGS} can cause bootstrap to fail

@samp{-O2 -g -mcpu=i686} on @code{i686-pc-linux-gnu} will cause bootstrap

failure as @option{-mcpu=} is deprecated in 3.4.0 and above.

@code{BOOT_CFLAGS} does not apply to bootstrapped target libraries.

Since these are always compiled with the compiler currently being

bootstrapped, you can use @code{CFLAGS_FOR_TARGET} to modify their

compilation flags, as for non-bootstrapped target libraries.

Again, if the native compiler miscompiles the stage1 compiler, you may
