Required header has been removed

[mtdew365]

/usr/include/bits/sigset.h has been removed upstream in the glibc-headers package.

Ubuntu... https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1720339

Fedora 27.... I don't see it in the latest version.

Error...

make[1]: *** No rule to make target '/usr/include/bits/sigset.h', needed by 'threads.o'. Stop.

Delete the .depsr directory and try again.
