How to compile git for solaris under ubuntu? (cross compile git)

I'm renting webspace with SSH access and I want to host a git repository
on it. I can log in using SSH and put websites up. However, git is not
installed on the server. Unfortunately, GCC is also not available on the
solaris box, or I couldn't find it. So, to find a solution, I've tried to
compile git myself for solaris (under ubuntu; I dont have solaris) and
then upload the compiled git to the webspace to use it there. That's what
I'm trying to do, but failed so far because while building the cross
compiler, I get the error
stdio.h: No such file or directory
in step "make all-target-libgcc"
which I could not resolve (google didn't help and I dont really know what
I'm doing there.)
Can you help me solve this? Or is there any alternative way to get git on
this solaris box?
On the solaris box:
> uname -a
SunOS gaffer 5.10 Generic_142901-13 i86pc i386 i86pc
I've described the same problem on superuser yesterday, but did not get
any answers:
