2999ed8613 change the way gcc's collect2 works to fix #74 
GCC's AIX port, which RetroPPC is based on, uses a different method
from most other platforms to collect the list of all global constructors
and the list of all exception handling tables.
The "standard" method does not work on AIX because IBM's linker will
discard those symbols too early for GCC's liking if they are not
directly referenced.

Unfortunately, the workaround seems to keep too much, so PPC C++
exececutables were at least 1.1MB big.

We don't need to be compatible with IBM's linker. Instead, hack binutils
to keep the symbols that we need kept, and allow GCC to use the
"standard" method for the collect2 pass.

PowerPC application sizes are now down to a reasonable size.
