Fix Solaris Ada bootstrap

[Rainer Orth]

Two of the latest Ada patches broke bootstrap on Solaris:

In file included from /vol/gcc/src/hg/trunk/local/gcc/ada/link.c:42:0:
./auto-host.h:1829:0: error: "_FILE_OFFSET_BITS" redefined [-Werror]
/var/gcc/regression/trunk/10-gcc/build/./prev-gcc/include-fixed/sys/feature_tests.h:197:0: note: this is the location of the previous definition
cc1plus: all warnings being treated as errors

auto-host.h has

/* Number of bits in a file offset, on hosts where this is settable. */
#ifndef USED_FOR_TARGET
#define _FILE_OFFSET_BITS 64
#endif

while <sys/feature_tests.h> defaults to 32 if undefined.  This can
easily be fixed by including auto-host.h before any system header.

i386-pc-solaris2.10 bootstrap is just in progress, but already past the
point of the previous failure.

Ok for mainline?

Thanks.
