gcc: Link libssp_nonshared.a only on musl targets
glibc already provides the content for libssp_nonshared in libc_nonshared.a therefore we dont need to make it universal. This also fixed build issues on glibc when linking statically and using -fstack-protector Fixed errors like /mnt/a/oe/build/tmp/work/i586-bec-linux/aufs-util/3.14+gitAUTOINC+bdfcc0dcfc-r0/recipe-sysroot/usr/lib/../lib/libc.a(stack_chk_fail.o): In function `__stack_chk_fail': /usr/src/debug/glibc/2.26-r0/git/debug/stack_chk_fail.c:27: multiple definition of `__stack_chk_fail_local' /mnt/a/oe/build/tmp/work/i586-bec-linux/aufs-util/3.14+gitAUTOINC+bdfcc0dcfc-r0/recipe-sysroot/usr/lib/../lib/libssp_nonshared.a(libssp_nonshared_la-ssp-local.o):/usr/src/debug/gcc-runtime/7.1.0-r0/gcc-7.1.0/build.i586-bec-linux.i586-bec-linux/i586-bec-linux/libssp/../../../../../../../../work-shared/gcc-7.1.0-r0/gcc-7.1.0/libssp/ssp-local.c:47: first defined here collect2: error: ld returned 1 exit status (From OE-Core rev: d71eba26850838b2878efea3f8c392a2eb2ebbfb) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

4Subject: [PATCH 40/49] Add ssp_nonshared to link commandline for musl targets
5
6when -fstack-protector options are enabled we need to
7link with ssp_shared on musl since it does not provide
8the __stack_chk_fail_local() so essentially it provides
9libssp but not libssp_nonshared something like
10TARGET_LIBC_PROVIDES_SSP_BUT_NOT_SSP_NONSHARED
11 where-as for glibc the needed symbols
12are already present in libc_nonshared library therefore
13we do not need any library helper on glibc based systems
14but musl needs the libssp_noshared from gcc
15
