make check fails with default libblas
...- This happens in three different systems, one using gcc-4.7.2 (Debian

- I have configured and compiled R trying to follow debian/rules in the
r-base-core package. This is what I do:

I think this is about the following line in debian/rules:
optimflags = `DEB_BUILD_MAINT_OPTIONS=optimize=-lto dpkg-buildflags --get CFLAGS`
https://sources.debian.org/src/r-base/4.4.0-2/debian/rules/#L101
...which later propagares to cxxflags = $(optimflags) and
eventually CXXFLAGS="$(cxxflags)" ... ./configure.

Without having looked in much detail, I guess foer the CXXFLAGS we want
dpkg-buildflags --get CXXFLAGS?
