does not find libraries on multi-arch debian

Libraries are located under /usr/lib/x86_64-linux-gnu not /usr/lib64

mentioned in commit 5ba2cbc5

mentioned in commit fe17c8ad

Still missing ptscotch on some systems, or incomplete handling of in32/int64.

Eg,

/usr/include/scotch-int32/libscotch-6.so
/usr/lib/x86_64-linux-gnu/scotch-int32/libscotch-6.so

/usr/include/scotch-int64/libscotch-6.so
/usr/lib/x86_64-linux-gnu/scotch-int64/libscotch-6.so

Although there doesn't seem to be anything for handling of float/double installs, can manage that with the PrecisionAdapator.
