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: cc937dad85 ("selftests: centralize -D_GNU_SOURCE= to CFLAGS in lib.mk")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
