Building TCC with the upcoming Mes 0.26

[Timothy Sample]

Hi,

I was able to build ‘tcc-boot’ (from Guix’s “commencement.scm”) with Mes
from the “wip” branch (on x86).  I had to update the ‘stage0-posix’
package to 1.6.0, and then it was a matter of two small issues.

The first was that I had to revert the ‘bootstrap.sh’ changes from
commit 0d3c4ddc4bcb57db690ee8ebab106fa6fda75823.  Not sure what that’s
about.  We might have to make the changes optional or something (maybe
there’s already a plan in place?).

The second was an issue with the ‘__raise’ stub.  It is fixed by the
attached patch.
