Use cmake specific options to enable position independent code generation.
This fixes several ports (at least multimedia/cmrtlib, math/blas and
math/lapack) which are build with cmake when WITH_PIE is enabled.

Haskell code benefits greatly from splitting functions into distinct ELF
sections and then letting the linker to garbage-collect them.
devel/hs-haskell-language-server port goes from 277MiB to 176MiB in size.
net-p2p/cardano-node ports goes 302MiB -> 76.2MiB

Add checks for powerpc64 and riscv64 since they won't work with LTO.
This is a bit crude on powerpc64 but can be improved upon later.
LTO does work on this platform using GCC but will fail using lld.
This commit also introduces LTO_DISABLE_CHECK which can be used to
override.
