[gentoo-dev] [PATCH] toolchain-glibc.eclass: Replace evar_* with local variables

["Michał Górny" <mgorny@gentoo.org>]

Use local variable to limit the scope of ABI variable override. This is
a builtin bash solution that is reliable and simple, unlike the complex
evar_* logic that unnecessarily pollutes global variables.
