configure: allow the gas-preprocessor to be called with an absolute path.
Allow the configure tool to call the gas-preprocessor with an absolute path when included with either the "--as" or with a separate "--gas" option. The patch is backward compatible and will not break any current configuration setups. The new behavior that comes with this option can be utilized in the following ways: Examples: - Just as single option that includes both the gas-preprocessor.pl and cc/as at the same time: $ configure --as="/opt/app/build-tools/gas-preprocessor.pl \ /Applications/Xcode.app/.../Developer/usr/bin/gcc" - Call gas-preprocessor with a separate option in conjunction with --as: $ configure --gas="/opt/app/build-tools/gas-preprocessor.pl" \ --as="/Applications/Xcode.app/.../Developer/usr/bin/gcc" - Address only the the gas-preprocessor and it will automatically fall back to as or cc whichever that's defined: $ configure --gas="/opt/app/build-tools/gas-preprocessor.pl" - Or if no gas-preprocessor.pl is explicitly defined, it falls back to the old behaivor.
