Link shared libasan with -z now on Solaris
g++.dg/asan/default-options-1.C FAILs on Solaris/SPARC and x86:
FAIL: g++.dg/asan/default-options-1.C -O0 execution test
FAIL: g++.dg/asan/default-options-1.C -O1 execution test
FAIL: g++.dg/asan/default-options-1.C -O2 execution test
FAIL: g++.dg/asan/default-options-1.C -O2 -flto execution test
FAIL: g++.dg/asan/default-options-1.C -O2 -flto -flto-partition=none execution test
FAIL: g++.dg/asan/default-options-1.C -O3 -g execution test
FAIL: g++.dg/asan/default-options-1.C -Os execution test
The failure is always the same:
AddressSanitizer: CHECK failed: asan_rtl.cpp:397 "((!AsanInitIsRunning() && "ASan init calls itself!")) != (0)" (0x0, 0x0) (tid=1)
This happens because libasan makes unportable assumptions about
initialization order that don't hold on Solaris. The problem has
already been fixed in clang by
[Driver] Link shared asan runtime lib with -z now on Solaris/x86
https://reviews.llvm.org/D156325
where it was way more prevalent.
This patch applies the same fix to gcc.
Tested on i386-pc-solaris2.11 (ld and gld) and sparc-sun-solaris2.11.

gcc:
* config/sol2.h (LIBASAN_EARLY_SPEC): Add -z now unless
-static-libasan. Add missing whitespace.
