Subject: haskell-cabal.eclass: respect AR option
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=e0cea5be7aaa1e47011de12743ca500f3bda4b8a;p=gentoo.git

haskell-cabal.eclass: respect AR option

That allows us to build not-so-broken static libraries
for LTO users. Tuhs usually have environment like:
    CFLAGS=-flto
    AR=${CHOST}-gcc-ar
