gcc: Fix libssh_nonshared linker specs for ppc/musl

Browse Source 
The change to link libssp_nonshared.a only for musl was to move
spec file changes to config/linux.h under a conditional when
DEFAULT_LIBC == LIBC_MUSL which worked fine for all but ppc
since gcc for ppc provided its own linux.h overrides which are
used. This patch duplicates the change in those headers too

Cherry-picked from oe-core master 9d39168a6acfa1f289a4448271c0bf9caaea10ec

(From OE-Core rev: 7d391a9e566a6ddc2970fc666a45570310bdc780)
