If you are asking specifically about Solaris w/ the vendor compilers, then
apparently Yes:
-bash-3.00$ cat test.c
#include <stdio.h>
int X = 0;
__attribute__((__constructor__)) void hello(void) { X = 42; }
__attribute__((__destructor__)) void goodbye(void) { printf("X = %d\n", X);
}
-bash-3.00$ cc -fPIC -c test.c
-bash-3.00$ cc -shared -o libtest.so test.o
-bash-3.00$ cat main.c
int main(void) { return 0; }
-bash-3.00$ cc main.c -L. -ltest
-bash-3.00$ ./a.out
X = 42
That is the ancient toolchain in /usr/bin:
-bash-3.00$ cc -V
cc: Sun C 5.9 SunOS_sparc 2007/05/03
usage: cc [ options] files. Use 'cc -flags' for details
-bash-3.00$ ld -V
ld: Software Generation Utilities - Solaris Link Editors: 5.10-1.489
Same result with Solaris Studio 12.3 compilers:
-bash-3.00$ cc -V
cc: Sun C 5.12 SunOS_sparc 2011/11/16
-bash-3.00$ cc -fPIC -c test.c
-bash-3.00$ cc -shared -o libtest.so test.o
-bash-3.00$ cc main.c -L. -ltest
-bash-3.00$ ./a.out
X = 42
