help
Enables --sysroot=dir for binutils and gcc.
Use dir as the logical root directory for headers and libraries.
For example, if the compiler would normally search for headers in
/usr/include and libraries in /usr/lib, it will instead search
dir/usr/include and dir/usr/lib.
This does not work with gcc < 4.2.0 (4.1.2 gets
ORIGINAL_AS_FOR_TARGET wrong)

For some platforms, proper stack unwinding works perfectly,
while other platforms must use setjmp/longjmp exceptions for
proper stack unwinding during exception handling. Most people
can leave this set to n.
