[Bug binutils/10916] New: Interprets --exclude-libs completely different to old GNU ld

[robert dot wohlrab at gmx dot de]

I have currently the problem that kde4libs doesn't build.

This is related to --exclude-libs specified on the commandline. The man page of
ld says "This option is available only for the i386 PE targeted port of the
linker and for ELF targeted ports".... "For ELF targeted ports, symbols
affected by this option will be treated as hidden". As it works with the old
linker without problem I would guess that the new linker just ommits everything
which is needed for the library specified by --exclude-libs. If I remove this
option the file gets linked also with binutils-gold.
