Document how to get started on other Linux distributions

[cblichmann]

Sandboxed API should build/work on all major Linux distributions.
We should provide at least some basic instructions for distributions other than Debian/Ubuntu:

• Fedora
• Arch Linux
• openSUSE
• Gentoo
  This also applies for their derivatives (CentOS, Manjaro, etc.)

Collecting the information for Fedora 29:

# Install Bazel (https://docs.bazel.build/versions/master/install-redhat.html)
sudo dnf install dnf-plugins-core
sudo dnf copr enable vbatts/bazel
sudo dnf install bazel

# Install necessary development tools
sudo dnf install patch gcc-c++ glibc-static libstdc++-static clang-devel \
  python2-clang python2-typing

# Force the use of the Gold linker
sudo alternatives --config ld
[ Select /usr/bin/ld.gold ]

Hi, i'm trying to embed te library and my current distribution is Arch Linux.
I have now some problems because i cannot compile correctly my library, but apart from that here are some hints i can give to write the Getting started for Arch based distributions:

• If using cmake libcap.a and libffi.so will be required, arch doesn't ship static libraries with packages so sudo pacman -S libcap won't solve the problem, i solved it by downloading the .tar for both libcap and libffi and followed the instructions from lfs site to compile them and install into the /usr/include path.
  Ps: I'll edit this comment in order to give more updates
