tcl::pkgconfig, proposed by TIP 59, a built-in Tcl command, first appeared in Tcl version 8.5.
dbohdan 2015-03-12: As of Tcl 8.6.3 the following information in available in through ::tcl::pkgconfig on Linux (with example values from Fedora 21).

| 64bit | 0 |
| optimized | 0 |
| mem_debug | 0 |
| compile_debug | 0 |
| compile_stats | 0 |
| libdir,runtime | /usr/lib64 |
| bindir,runtime | /usr/bin |
| scriptdir,runtime | /usr/share/tcl8.6 |
| includedir,runtime | /usr/include |
| docdir,runtime | /usr/share/man |

I found the *,runtime values useful in building tcl-augeas|a Tcl extension without having to resort to autoconf on systems with no information about Tcl available from pkg-config (e.g, Ubuntu).
