[gentoo-dev] [PATCH] eclass/ruby-fakegem.eclass: set flags for compilation

[Hans de Graaff]

Explicitly pass CC, CFLAGS and LDFLAGS when compiling ruby
extensions. By default ruby re-uses the stored flags used when
compiling ruby itself. This is intended to create a better chance of
compatibility between extensions and ruby itself, and extensions do
not need to bother with this themselves, but it does not match the
expectations of a Gentoo system where each compile action should use
the currently defined flags.

We also cannot guarantee this compatibility in any case since
toolchain packages may have been updated in the meantime.

This change uses the current CC, CFLAGS and LDFLAGS, and adds -fPIC
which ruby extensions need and which would otherwise be added by
ruby. This combination is already used in some ebuilds without any
reported issues.
