Building postgresql armv7 on emulated x86_64

Hi,

I cannot compile postgresql for armv7. I tested a bunch of versions of gcc
and all have the same issue. Sometimes disabling optimization allows me to
compile failed files but it is not a rule. The same error will happen in
another file and changing optimization parameters or lto options does not
make a difference.

Problem is related to dtrace probes code. Compiling without them is
successful.

Maybe someone encountered something similar. I'm using Fedora Rawhide. Here
is the error:

<mock-chroot> sh-5.1# gcc -I../../../../src/include -I/usr/include/libxml2
