Probably it's my attempt to make it work with non-static libm that failed then,

is it supposed to work?

I see mention of BUILD_STATIC there, but it does not seem to actually work for me.

If I use static libm, then it works.
If I uninstall static libm, any attempt to build fails, regardless of whether I pass BUILD_STATIC='n' or so.

Ciao and thanks,
