Add support for external spec file via the GCC_SPECS env var. This
|
|
allows us to easily control pie/ssp defaults with gcc-config profiles.

Original patch by Rob Holland

Extended to support multiple entries separated by ':' by Kevin F. Quinn
|
|
Modified to use getenv instead of poisoned GET_ENVIRONMENT by Ryan Hill
