Support older hosts with latest util-linux-native
mkostemp is not defined on older machines. So we detect this and
provide a define that uses mkstemp instead.
O_CLOEXEC is not defined on older machines. It is however defined
in the 'c.h' header. Fix up the users to include 'c.h'.
fdisks/fdisksunlabel.c was modified to use qsort_r, however
this is not defined on older hosts. Revert:
commit c69bbca9c1f6645097bd20fe3a21f5a99a2a0698
fdisk: (sun): use ask API, remove global variable
Upstream-Status: Inappropriate [other]
Patches revert upstream changes in order to support older
machines.
