It is set that way probably because dri's configure script really
did _set_ HAVE_LIBDRM_RADEON=yes.

And it probably set HAVE_LIBDRM_RADEON=yes because there is something
non-standard on your system.

Let's look at part of the dri configure script...

        if test -n "$PKG_CONFIG" && \
    { { $as_echo "$as_me:${as_lineno-$LINENO}: \$PKG_CONFIG --exists --print-errors \"libdrm_radeon libdrm >= \$LIBDRM_RADEON_REQUIRED\""; } >&5
  ($PKG_CONFIG --exists --print-errors "libdrm_radeon libdrm >= $LIBDRM_RADEON_REQUIRED") 2>&5
  ac_status=$?
  $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5
  test $ac_status = 0; }; then
  pkg_cv_LIBDRM_RADEON_LIBS=`$PKG_CONFIG --libs "libdrm_radeon libdrm >= $LIBDRM_RADEON_REQUIRED" 2>/dev/null`


So what does 'pkg-config --exists --print-errors "libdrm_radeon libdrm"'
show on your system?

The configure script should only set HAVE_LIBDRM_RADEON=yes if the
above succeeds.

If it does succeed, then somehow you got libdrm_radeon (i.e.,
libdrm_radeon.pc) installed.  But that should not be installed
if libdrm is built with --disable-radeon-experimental-api (as
it is currently set to be built in graphics/libdrm 2.4.17).

config.log might also tell more.
