sci-libs/tensorflow: build with -std=c++14 in 2.5.0-r1
TensorFlow is not yet compatible with the C++17 dialect. Allow it to
build with gcc:11 by appending -std=c++14 to CXXFLAGS, prior to composing
bazelrc. The flag doesn't encompass the building of the ruy library, so
this is accompanied by a patch to include the <limits> header in the one
place that ruy needs it.
Filter out the -fvtable-verify=@(std|preinit) flag, if present. While
ostensibly useful for hardening, it prevents TensorFlow from building
successfully. Note that, while the pattern is in the form of an
extglob, the accompanying shopt does _not_ need to be enabled.
Have src_install localise "l", rather than "j", because the function in
question never employs the latter.
Closes: https://bugs.gentoo.org/787938
