Something's definitely messed up there:

Looking at this example of a v10 build log on macOS:
https://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=longfin&dt=2017-10-23%2018%3A15%3A34&stg=make

the compile command for autoinc is

ccache gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -Wno-unused-command-line-argument -g -O2 -fno-common -Wno-deprecated-declarations -Werror -DREFINT_VERBOSE -I. -I. -I../../src/include -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/libxml2 -I/usr/local/ssl/include -c -o autoinc.o autoinc.c

Some of the discrepancies (e.g. -Werror on the buildfarm machine) are
explainable as different configuration choices, but the references to
/usr/local/pgsql965 in your build sure look like trouble.

I believe the configure script *does* pay attention to environment
variables, particularly CPPFLAGS and CFLAGS. Most likely you had
version-specific values in those when you ran configure, and they
got absorbed into src/Makefile.global.
