The diagnosis by Bennet Fauber, that
LDFLAGS='-specs=/usr/lib/rpm/redhat/redhat-hardened-ld'
is the problem, that LDFLAGS='-Wl,-z,relro -Wl,--as-needed -Wl,-z,now'
works OK, and that the -specs= conflict with autoconf has not been
resolved seems accurate to me (see also
https://developers.redhat.com/blog/2018/03/21/compiler-and-linker-flags-gcc/,
https://bugzilla.redhat.com/show_bug.cgi?id=1343892).
I realise that the R RPM needs to follow RH/F standards, but has something
happened in the RPM ecosystem recently to poison the -spec/autoconf
relationship?
Did something change in rgdal's flags from 1.5-10 to 1.5-12? Because
the former installs fine. You can see in [1] that it fails since the
last update.
I see that rgdal changed to C++ recently. The issue is in rgdal,
because the configure script is missing:
CXXFLAGS=`"${R_HOME}/bin/R" CMD config CXXFLAGS`
as indicated in Writing R Extensions (note that CPPFLAGS are *not*
CXXFLAGS; I say this because it's a common mistake).
Thanks, added R-forge revision 1021. The problem was caused by the
addition of AC_LANG(C++) (about line 500, 11 June) in connection with
preparations for macOS static builds; without AC_LANG(C++) Fedora runs
configure OK. With AC_LANG(C++), Fedora needs CXXFLAGS set if using the R
rpm (otherwise and other systems not). CPPFLAGS were used for the C
pre-processor.

Did something change in rgdal's flags from 1.5-10 to 1.5-12? Because
the former installs fine. You can see in [1] that it fails since the
last update.
