@(textproc/R-readxl) fix build against R-4.6.0
@

@$NetBSD$

- The Problem is:
  RcppEigen.so: Undefined PLT symbol "backtrace_symbols" (symnum = 108)

- The symbol "backtrace_symbols" is defined in /usr/lib/libexecinfo
  at *BSD OS

- R package does not honor LIBS+= parameter, due to real build is done
  at (pkgsrc) install stage

- Neither bmake (.if eq ... .endif) nor gmake ( ifneq .. endif) does work
  in src/Makevars

- So the condition branch will be done at SUBST mechanism
