Comment (by sergeish):

 Thanks @robe.

 My conclusion was that PGXS has to be replaced, since it intoduces another
 set of compilation options that is not fully controlled by user. It seems
 that LTO cannot be reliably enabled by default before doing that,
 especially if we need to allow selecting CC in `./configure` like in this
 failing tests.

 Thank you for mentioning @strk's opinion. Would be great if he could
 comment on this issue.

 `CUSTOM_CC := $(CC)` was my attempt to make PGXS use the same compiler.
 Seemed to work in my case, but later I noticed `cc` being used as compiler
 in log.
