make hardened compiler flags optional
First note: the default behavior is unchanged.
For people building tlsdate themselves with a known toolchain env, the
checked flags can be redundant, or even harmful. A compile/link check
for PIE behavior for example might not catch the full supported status
for some architectures/C libraries.
Further, the current code starts by throwing away the user's compiler
settings which can also be harmful. Those often times include settings
related to ABI or target cpu selection and ignoring them can produce an
unusable binary.
So add a flag that people (including distros) can leverage to bypass
all of the checks.
