I fear the proposed fix is what piglit and many others tend to do.
Here are some of the files containing such workarounds:

tests/egl/egl-configless-context.c
tests/glx/glx-buffer-age.c
tests/glx/glx-context-flush-control.c
tests/spec/ext_image_dma_buf_import/image_common.h
tests/spec/gl-3.0/api/clearbuffer-invalid-buffer.c
tests/spec/glx_mesa_query_renderer/query-renderer-common.h
tests/spec/oes_compressed_etc1_rgb8_texture/oes_compressed_etc1_rgb8_texture-basic.c
tests/util/glxew.h


A few other suggestions:
 - Check that the headers are new enough and bail out early in cmake.
Unfortunately distros may insist on keeping old headers, despite that
updating (and using) them won't cause ABI breakage.
 - Have a local copy of the headers in-tree.
Could get ugly, but many projects seems to be doing it.

I'm leaning towards the former, although feel free to use whichever you fancy.
