PROVIDE_HIDDEN etc. were removed by
8733f6093c2b77502e7228503fc22024e51599b8 in order to support BSDs with
older binutils (2.15). Maybe the ld scripts should be generated from a
source file for example with CPP, so these lines could be tweaked.
Doesn't guest base make the whole ld script thing useless? It's not
implemented for Sparc though.
