[OE-core] [PATCH 16/22] gcc: Fix libssh_nonshared linker specs for ppc/musl

[Khem Raj]

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
