My name is Denis, I work on gentoo linux
There is an issue waiting to be resolved
We have failed with configuring ncurses because of flto flag set in CFLAGS, 
CXXFLAGS, LDFLAGS since some conftests cheking linking with dl*() functions 
work unexpectedly for the configure script when 'flto' is on. The gist is that 
'flto' makes a compiler and a linker displace some symbols like 'dlsym' because 
they are not used actually; without 'flto' everything works because no 
optimization is taken and every symbol used appears when linking, no one is 
optimized out
This is the gentoo issue https://bugs.gentoo.org/606142, take a look please

Thank you
