use the correct attributes for ___errno_location
In the public header, __errno_location is declared with the "const" attribute, conditional on __GNUC__. Ensure that its internal alias has the same attributes. Maintainer's note: This change also fixes a regression in quality of code generation -- multiple references to errno in a single function started generating multiple calls again -- introduced by commit e13063aad7aee341d278d2a879a76ec7b59b2ad8.
