Change int8_t to signed char on Solaris [PR113450,PR123176]
a couple of D test fail:
UNRESOLVED: gdc.test/runnable_cxx/stdint.d compilation failed to produce
executable
Undefined first referenced

This happens because the mangling of int8_t was changed.
The probably can easily avoided by adjusting libdruntime's idea of
int8_t as in the attached patch.
Bootstrapped without regressions on i386-pc-solaris2.11 and
sparc-sun-solaris2.11.
Ok for trunk?
In general, libphobos patches need to go upstream first. In this case,
however, the change is specific to GCC trunk since it depends on the
fixed definitions of int8_t etc., so it may be TRT to apply it to the
GCC tree only.
Thanks.
