Hello,

This change adjusts the processing of --sysroot to save the option in the
internal "switches" array, which lets self-specs test for it and provide a
default value possibly dependent on environment variables, as in

   --with-specs=%{!-sysroot*:--sysroot=%:getenv("WIND_BASE" /target)}

This helps the use we have of self specs for VxWorks, and
was bootstrapped and regression tested on native 64bit linux.

Ok to commit ?

Thanks in advance,

With Kind Regards,

Olivier

OK.
