Those were *backticks*, and the workround would need to be applied on
the command line (since gprbuild can't execute arbitrary shell commands
internally).
If you say
gprbuild -P foo -largs -Wl,-macosx_version_min,`sw_vers -productVersion`
under a Unix-type sh-like shell (e.g. bash), the shell will execute the
part in backticks and substitute the result (in this case, 10.12.3) in
the command line actually passed to gprbuild.
I suppose you could set up an environment variable
export OS_VER=`sw_vers -productVersion`
and use 'case' magic inside your GPR.
