Drop dolt

Dolt only made a noticable difference with old libtool versions.
With libtool 2.2.10, the speed difference is < 5% in "make -j8"
builds I tried.

"time make -j8" output of 3 runs before the patch and 3 runs with this patch on an Intel 
i7-860 with 8 GB of RAM:

With dolt:

real    8m48.871s
user    63m5.526s
sys     4m14.357s

real    8m43.389s
user    63m14.902s
sys     4m15.006s

real    8m44.677s
user    63m15.848s
sys     4m14.686s


Without dolt:

real    9m8.344s
user    64m31.824s
sys     4m24.658s

real    9m8.492s
user    64m30.652s
sys     4m24.363s

real    9m6.837s
user    64m32.277s
sys     4m24.979s


The fabulous speed increase in the email linked from https://bugs.webkit.org/show_bug.cgi?id=19395#c3 were against libtool 1.5 that was already obsolete of the time of that email.
