known issues with --rpath support

[boegel]

• RPATH sanity check with default paths fails on binary installations (see rpath sanity check crashes when installing java #2039, fix in skip RPATH sanity check for binary installations easybuild-easyblocks#1056)
• locations in build directory and temporary directory should not get RPATH'ed (fixed in add support for RPATH linking (REVIEW) #1942)
• rpath_wrapper_template.sh.in is not packaged in EasyBuild v3.0.0 (boostraping easybuild-3.0 does not install rpath_wrapper_template.sh.in #2006, fix in fix packaging issue with non-Python scripts in easybuild/scripts #2015)
• install numpy as extension yields a traceback under --rpath (rpath's sanity check crashes when building numpy #2009, fix in make sure 'modules_tool' attribute is also defined for extensions #2026)
• wrapper script used when building extensions should the actual compiler command, not an existing wrapper script (Easybuild with rpath support enabled is really slow when building extensions. Easybuild launches many processes #2010, fix in avoid rewrapping already wrapped compiler/linker command with RPATH wrapper script #2022)
• toolchain option to selectively disable RPATH linking (toolchainopts = {'rpath': False}, fixed in add 'rpath' toolchain option to selectively disable use of RPATH wrappers #2047 + skip RPATH sanity check when toolchain did not use RPATH wrappers #2052)
• take -r option into account in rpath_args.py (see take -r option into account in rpath_args.py #2040)
• add option to install RPATH wrapper script together with compiler/toolchain modules
• support notion of linkdependencies (see add support for 'linkdependencies' easyconfig parameter (WIP) #1960)
• current RPATH implementation breaks virtualenv due to use of $ORIGIN (see RPATH with Python and virtualenv #2076)
• MySQL-Python installation is broken under --rpath (see problem building MySQL-python python extension with rpath #2054)
• mpi4py is broken under --rpath (see problem building Python-2.7.5-ictce-6.2.5.eb and mpi4py extension with --rpath #2055)
• support both RPATH and RUNPATH
• known issues with RPATH sanity check
  • some easyblocks need to specialise the locations for the RPATH sanity check (e.g. OpenFOAM, see OpenFOAM escapes RPATH sanity check easybuild-easyblocks#1193)
  • ParaView: needs to add additional locations to RPATH in (../lib/paraview-%(version)s)
  • VTK: inject additional locations in link.txt files for Python bindings
  • PETSc: requires --LDFLAGS=-lintc to dance around problem with librng.so library not finding libintc.so
  • failing RPATH sanity check for Augustus, Modeller, MRtrix3, no RPATH linking for dependency libraries? (reported by @pescobar)

Are there more details about the remark 'some easyblocks need to specialise the locations for the RPATH sanity check (e.g. OpenFOAM)'? I have been able to install OpenFOAM 2.3.1 using the --rpath support without any tweaks. I could install OpenFOAM-4.0 using the --rpath support with an additional line to the easyconfig for the ParaView installation.

@jdonners I created a new issue for the OpenFOAM issues at easybuilders/easybuild-easyblocks#1193
