[tlbuild] The new dvisvgm no longer compiles on Solaris

[Mojca Miklavec]

Hi,

On Solaris the new dvisvgm no longer compiles as it doesn't know
whether to calculate pow(int, int) as pow(float, float) or pow(double,
double).

But I'm not 100% sure and didn't have time to try out casting those numbers yet.
