[R-sig-Fedora] Fedora 42 R source build issues

[peter dalgaard]

The Mac builds want stuff like below. I suspect you may need similar tcl and tk lines pointing to *Config.sh for Tcl/Tk 8.

(Tcl/Tk 9 popped up a bit too late in the development cycle for us to go investigating. Do you have any specifics about what has changed and causes problems?)

-pd

pd$ more config.site
CPPFLAGS=-I/opt/R/x86_64/include
LDFLAGS=-L/opt/R/x86_64/lib
with_tcl_config=/opt/R/x86_64/lib/tclConfig.sh
with_tk_config=/opt/R/x86_64/lib/tkConfig.sh
