6.12-stable review patch. If anyone has any objections, please let me know.

From: Jan Stancek <jstancek@xxxxxxxxxx>
[ Upstream commit 23b3a7c4a7583eac9e3976355928a832c87caa0f ]
Package build environments like Fedora rpmbuild introduced hardening
options (e.g. -pie -Wl,-z,now) by passing a -spec option to CFLAGS
and LDFLAGS.
mptcp Makefile currently overrides CFLAGS but not LDFLAGS, which leads
to a mismatch and build failure, for example:
make[1]: *** [../../lib.mk:222: tools/testing/selftests/net/mptcp/mptcp_sockopt] Error 1
/usr/bin/ld: /tmp/ccqyMVdb.o: relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: failed to set dynamic section sizes: bad value
collect2: error: ld returned 1 exit status
Fixes: cc937dad85ae ("selftests: centralize -D_GNU_SOURCE= to CFLAGS in lib.mk")
