[oe] [PATCH] autotools.bbclass: Specify a value of sysroot instead of asking the compiler

[Khem Raj]

If we just use --with-libtool-sysroot then it asks the compiler at
configure time to supply the sysroot which will not work with external
toolchains because they may have different default sysroot encoded into
them. Therefore we specify the sysroot so the configure can use that
value and not depend upon compiler to supply one.
