combrelocs improves startup time

[Bryce McKinlay]

Some good news: the new "combreloc" linker feature, which is on by 
default if you use linux binutils 2.12.90.0.1 with a recent glibc, gives 
a measurable improvement in the libgcj startup cost...

before:
$ LD_DEBUG=statistics ./a.out
04296:                   number of relocations: 47776
04296:        number of relocations from cache: 604

after:
$ LD_DEBUG=statistics ./a.out
23496:                   number of relocations: 16973
23496:        number of relocations from cache: 33451

On my PowerBook, the runtime for a "hello world" dropped from ~0.15s to 
~0.11s.

Bryce.
