Fix gdc testsuite failures on Solaris

This patch fixes two gdc testsuite failures on Solaris:

UNRESOLVED: gdc.test/runnable/dhry.d   compilation failed to produce executable
UNRESOLVED: gdc.test/runnable/dhry.d -shared-libphobos   compilation failed to produce executable

gdc.test/runnable/dhry.d:489:16: error: undefined identifier 'dtime'
gdc.test/runnable/dhry.d:543:14: error: undefined identifier 'dtime'

In line with the existing code, I've added yet another (identical)
implementation of dtime.  However, to avoid further duplication, it's
probably way better to introduce (say) version (Have_Gettimeofday)
instead.

The other failures is

UNRESOLVED: gdc.test/runnable/cppa.d   compilation failed to produce executable
UNRESOLVED: gdc.test/runnable/cppa.d -g   compilation failed to produce executable
UNRESOLVED: gdc.test/runnable/cppa.d -g -shared-libphobos   compilation failed to produce executable
UNRESOLVED: gdc.test/runnable/cppa.d -shared-libphobos   compilation failed to produce executable

In file included from gdc.test/runnable/extra-files/cppb.cpp:36:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/../../libstdc++-v3/libsupc++/exception:37:10: fatal error: bits/c++config.h: No such file or directory
compilation terminated.

It turns out that one the -I flags added by is wrong for the non-default
multilib:

$objdir/gcc/testsuite/gdc1/../../gdc -B$objdir/gcc/testsuite/gdc1/../../ gdc.test/runnable/cppa.d -m64 -fno-diagnostics-show-caret -fno-diagnostics-show-line-numbers -fdiagnostics-color=never -I$objdir/i386-pc-solaris2.11/amd64/libphobos/libdruntime -I$srcdir/gcc/testsuite/../../libphobos/libdruntime -I$srcdir/gcc/testsuite/../../libphobos/src -I$objdir/i386-pc-solaris2.11/amd64/libstdc++-v3/include -I$objdir/i386-pc-solaris2.11/amd64/libstdc++-v3/include/amd64 -I$srcdir/gcc/testsuite/../../libstdc++-v3/libsupc++ -I$srcdir/gcc/testsuite/gdc.test/runnable gdc.test/runnable/extra-files/cppb.cpp -B$objdir/i386-pc-solaris2.11/amd64/libphobos/src -L$objdir/i386-pc-solaris2.11/amd64/libphobos/src/.libs -L$objdir/i386-pc-solaris2.11/amd64/libphobos/libdruntime/.libs -L$objdir/i386-pc-solaris2.11/amd64/libstdc++-v3/src/.libs -lm -o ./cppa.exe

While bits/c++config.h is in

  i386-pc-solaris2.11/amd64/libstdc++-v3/include/i386-pc-solaris2.11

gdc searches .../libstdc++-v3/include/amd64 instead which doesn't
exist.  This needs to be $target_triplet instead, which lets the test
PASS for both the default and the 64-bit multilib.  The same issue
exists with multilib testing on Linux, btw.

Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.  Ok for mainline?

	* gdc.test/runnable/dhry.d [Solaris]: Import
	core.sys.posix.sys.time.
	(dtime): Define.
	* lib/gdc.exp (gdc_include_flags): Declare target_triplet.
	Remove target.
	Use $target_triplet in C++ include path.
