Read that page again:
If you wish to use non-default GCC flags when compiling the stage2 and stage3 compilers, set 
BOOT_CFLAGS on the command line when doing make bootstrap. Non-default optimization flags 
are less well tested here than the default of -g -O2, but should still work. In a few cases, you may 
find that you need to specify special flags such as -msoft-float here to complete the bootstrap; or, 
if the native compiler miscompiles the stage1 compiler, you may need to work around this, by 
choosing BOOT_CFLAGS to avoid the parts of the stage1 compiler that were miscompiled, or by 
using make bootstrap4 to increase the number of stages of bootstrap.
