Bug#870445: libglvnd: FTBFS on non-Linux: u_execmem_free undefined

["Aaron M. Ucko" <ucko@debian.org>]

Source: libglvnd
Version: 0.2.999+git20170201-4
Severity: important
Tags: upstream
Justification: fails to build from source

Builds of libglvnd for kFreeBSD and the Hurd (admittedly not release
architectures) have been failing:

  ./build/src/GLdispatch/vnd-glapi/../../../../src/GLdispatch/vnd-glapi/stub.c:110: undefined reference to `u_execmem_free'

Could you please take a look?

Thanks!
