# the underlying GCC. In order to get verbose output from the latter
# at both compile and linking stages, we need to call NAG with two
# additional flags: '-Wc,-v' and '-Wl,-v'. However, we return only
# '-Wl,-v' for the following reasons:
# 1) the interface of this method does not support multiple flags in
# the return value and, at least currently, verbose output at the

# 2) NAG is usually mixed with GCC compiler, which also accepts

# to the linker and the latter produces verbose output for the
# linking stage ('-Wc,-v', however, would break the compilation
# with a message from GCC that the flag is not recognized).
#
# This way, we at least enable the implicit rpath detection, which is
# based on compilation of a C file (see method
# spack.compiler._compile_dummy_c_source): in the case of a mixed
