[PATCH 20.11] config/ppc: fix build with GCC >= 10

[luca.boccassi at gmail.com]

From: David Marchand <david.marchand at redhat.com>

[ backported from upstream commit dfb1ad1e7a070926c9bd9fdf38e6b944a21f1d49 ]

Like for python, multiline statements in meson must either use a
backslash character (explicit continuation) or be enclosed in ()
(implicit continuation).

python PEP8 recommends the latter [1], and it looks like meson had
an issue with backslash before 0.50 [2].

Fixes: 394407f50c90 ("config/ppc: ignore GCC 11 psabi warnings")
