Hmm, weird.  Defines were my first idea, the diff of all defines used in
the compile is:

 -DGLX_DIRECT_RENDERING
 -DGLX_INDIRECT_RENDERING
 -DGLX_SHARED_GLAPI
 -DGLX_USE_TLS
 -D_GNU_SOURCE
 -DHAVE_ALIAS
+-DHAVE_DLFCN_H=1
+-DHAVE_INTTYPES_H=1
+-DHAVE_LIBEXPAT=1
 -DHAVE_LIBUDEV
+-DHAVE_LIBXCB_DRI2=1
+-DHAVE_MEMORY_H=1
 -DHAVE_MINCORE
 -DHAVE_POSIX_MEMALIGN
+-DHAVE_STDINT_H=1
+-DHAVE_STDLIB_H=1
+-DHAVE_STRING_H=1
+-DHAVE_STRINGS_H=1
+-DHAVE_SYS_STAT_H=1
+-DHAVE_SYS_TYPES_H=1
+-DHAVE_UNISTD_H=1
 -DHAVE_XCB_DRI2
 -DHAVE_XCB_GLX_CREATE_CONTEXT
 -DIN_DRI_DRIVER

+directory.

The MAPI ones are a bit concerning, but the consumer of ABI_HEADER
#errors if it's not defined, and defining MAPI_MODE_BRIDGE doesn't
change the resulting libGL.so here.  The extra HAVE_* defines shouldn't
do anything.

Could you stick a debugger on it and see where it's stopped, at least?
