Using LTO with libtool

[Schrober]

Hi,

I wanted to use link-time optimization (LTO/-flto) of GCC with libtool. I 
thought I only have to add "-flto" to CFLAGS and LDFLAGS and then I am 
finished. But it seems that this is not enough because some CFLAGS aren't 
copied to the linker command (e.g. -g). This results in a binary with missing 
information. Is there a differrent "correct" way to use libtool (through 
automake) with LTO?

Regards
