Unfortunately, this breaks all Go link tests on Solaris 10:
output is:
Undefined first referenced
symbol in file
dl_iterate_phdr
/var/gcc/gcc-4.8.0-20121010/10-gcc-gas/i386-pc-solaris2.10/./libgo/.libs/libgo.so
ld: fatal: symbol referencing errors. No output written to
/var/gcc/gcc-4.8.0-20121010/10-gcc-gas/gcc/testsuite/go/array-1.x
collect2: error: ld returned 1 exit status
FAIL: go.go-torture/execute/array-1.go compilation, -O0
Solaris 10 Update 10 or sufficiently recent linker patches introduced
dl_iterate_phdr on S10 as a backport from Solaris 11, but unlike S11, it
lives in libdl.so only. The current dl_iterate_phdr check misses that,
and given that it's only available in the most recent update, it's
probably best to avoid d_i_p on Solaris 10 altogether.
