Increase rtld initial memory pool size from 32kB to 128kB.
The old value was probably fine back in 1998, when that code was imported (although the comments still mention VAX, which was quite obsolete by then); now, however, it's too small to handle our libc, which results in some additional calls to munmap/mmap later on. Asking for more virtual address space is virtually free, and syscalls are not, thus the change. It was suggested by kib@ that this might be a symptom of a deeper problem. It doesn't only affect libc, though - the change also improves rtld memory management for eg KDE libraries. I guess it's just a natural bloat.
