I've added these suggested changes. Also, I was advised by the libamath team that the complicated relationship between libamath and libm needs more elaborate handling, hence additional `-lm` before `-lamath` (see comment that I've also added). Also I was advised to use `--as-needed`, so I wrapped it around push/pop-state.
