mk/config.mk.in: lower -O2 optimization down to -O1 on UNREG
Disable -O2 optimization. Otherwise amount of generated C code makes
things very slow to compile (~5 minutes on core-i7 for 'compiler/hsSyn/HsExpr.lhs')
And sometimes not compile at all (powerpc64 overflows something
on 'compiler/hsSyn/HsExpr.lhs').
Issue #8748
