buildsys: shorten abi dep-file names

Browse Source 
certain crypto-layers encode required information in the
filename hence crippling NAME_MAX from 255 down to about 143
ascii chars.

Since the dependency files of libgcc_eh and libsupc encode the full
path to the corresponding libraries, the names of the dep files can
get quite large. Shorten them by some (arbitrary, short) hash.
