disable some warnings in make options for compressible

use the default 7 hexadecimal digits as the abbreviated object name;
disable warnings about old-style casts, unused results and literal
suffix, since they are of little interest and mostly caused by external
libraries (mpi, c/c++ standard libraries)
(same as in 80aaf69748 and
9e478e23a6)
