tpm2-totp uses _DEFAULT_SOURCE to make the htobe64() macro available,
support for which was only added in glibc 2.20:
https://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html#index-_005fDEFAULT_005fSOURCE
>From glibc 2.20 NEWS:
* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
supported; they now act the same as _DEFAULT_SOURCE (but generate a
warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
conflicted with POSIX (support for which was removed in 2.19), the
interfaces those macros enabled remain available when compiling with
_GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
test macros defined.
This could be worked around by defining _BSD_SOURCE for this old toolchain
(cannot be done unconditionally as it generated warnings for modern glibc
versions), but given that platforms using this old toolchain are unlikely to
have a TPM 2.0 and use it for TOTP, simply blacklist it instead.
