Patch currently used in Solaris builds

The glib configure script fails to detect that Solaris ld supports -z nodelete:

checking for -z,nodelete linker flag... no

config.log shows it failed due to:

configure:29135: checking for -z,nodelete linker flag
configure:29149: gcc  -m64 -o conftest -std=gnu11 -Wall -Wextra -Wwrite-strings -Wmissing-noreturn -Wmissing-format-attribute -Wstrict-aliasing -Wno-unused-parameter -idirafter  /usr/gcc/5/lib/gcc/x86_64-pc-solaris2.12/5.4.0//install-tools/include -Wstack-usage=1048576 -Wdate-time -O2  -m64 -g -I/net/also.us.oracle.com/export/alanc/X.Org/amd64-gcc/install/usr/X11R7/include -DNO_ALLOCA -D__EXTENSIONS__ -D_REENTRANT -D_ERRNO_VERIFY -D__C99FEATURES__  -D__unix__ -D_REENTRANT -D_PTHREADS -Wl,--fatal-warnings -Wl,-z,nodelete conftest.c  >&5
ld: fatal: option '-z nodelete' is incompatible with building a dynamic executable
collect2: error: ld returned 1 exit status

Ensuring that the flags to build a shared library are also passed when testing
this flag cause it to be correctly detected:
