Fails to compile with GCC 7.2.0

Trying to compile the Halide master python bindings with GCC 7.2.0 on Ubuntu 16.04 (Python 3.6, GCC) gives the following error:

What configuration works to build the python bindings for Python 3.6 on Ubuntu?

[jwfromm]

Turns out adding -fno-lto to the LDFLAGS resolves this issue.

I met this problem when compiling libxml in Linux. I tried this but it doesn't work. Then I add --disable-shared when ./configure, everything goes normal.
