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.
