[gentoo-dev] [PATCH] sys-libs/ncurses: Use --cache-file to speedup subsequent econf runs

[Michał Górny]

Use --cache-file to reuse the previous check results in the subsequent
configure script runs. This gives a major speed advantage (beating the
previous parallel runs) and significant CPU savings.
