#    Description:
#       stressapptest is a userspace test, primarily composed of
#       threads doing memory copies and directIO disk read/write.
#       It allocates a large block of memory (typically 85% of the
#       total memory on the machine), and each thread will choose
#       randomized blocks of memory to copy, or to write to disk.

# We explictly remove plug-in '*.la' files because some packages that
# depend on these libraries use libtool. If libtool finds a '*.la'
# file for a library, it uses the value of 'libdir=<dir>' it finds. In
# our case, since '--prefix=/usr' this value is '/usr/lib'. It then
# resolves '-lfoo' to '/usr/lib/libfoo.so'. In a cross-compilation
# environment, this is likely to be neither the right architecture nor
# the right version to link against. In short, we lose.
#
# We could also handle this by removing DESTDIR and setting the prefix
# to $(ResultDirectory); however, that results in libtool hard-coding
# $(ResultDirectory) as the RPATH in the linked executables which is
# NOT what we want either. We lose again.
#
# By removing the '*.la' file, we win by ensuring neither a misdirected
# link nor an RPATH.
