With many thanks to ulm for having pointed this out. Not that while this
patch does indeed change the eclass behaviour for the established EAPI 7
rather than for the new EAPI 8, it does so in a way I deem non-intrusive
enough to allow this - the only case where something is actually removed
from DEPEND is when Fortran is only required by tests. Not to mention
that, ahem, there is considerable room for improvement as far as the
uptake of EAPI 7+ among consumers of this eclass is concerned.

[gentoo-dev] [PATCH] fortran-2.eclass: use BDEPEND on EAPI 7+

[Marek Szuba]

For FORTRAN_NEEDED=test we need both the compiler and the test binaries
to run on the build host only, hence new EAPIs only set BDEPEND here;

For other modes (other than "no", of course), we need a Fortran compiler
running on the build host as well as the runtime libraries built for the
target arch, necessitating the use of both DEPEND and BDEPEND on newer
EAPIs.
