package/ibm-sw-tpm2: re-fix build with uClibc-ng and older glibcs In commit 26e37cef1627faa1f5ab8935482e2b2bc3465c33, we started using __WORDSIZE to get the size of longs on the given architecture, in order to support all CPU architectures. Unfortunately, __WORDSIZE is not enabled in musl, so in 19bd08900448aa45b506320ad2ab912f789e6e5e, we switched to using LONG_BIT instead of __WORDSIZE. However, LONG_BIT is not readily available on glibc, you need _XOPEN_SOURCE to be defined, which was done in a34e7f88f67b77066f73894dc8e42bca3c076fa6. However, in a34e7f88f67b77066f73894dc8e42bca3c076fa6, _XOPEN_SOURCE was just defined, with no specific value. This caused the build to break again on uClibc-ng and older glibcs, because clock_gettime() and CLOCK_MONOTONIC were no longer defined. In both uClibc-ng and glibc, CLOCK_MONOTONIC is only defined if __USE_POSIX199309 is defined. It turns out that simply defining _XOPEN_SOURCE with no value does not lead to __USE_POSIX199309 being defined in uClibc-ng and old glibcs, while it is defined in newer glibcs. The difference comes from the following snippet of code, which is present in recent enough glibc's <feature.h> but not uClibc-ng's or older glibc's <feature.h>: /* If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE is defined, use POSIX.1-2008 (or another version depending on _XOPEN_SOURCE). */ So the fact that we are defining _DEFAULT_SOURCE makes it assume that we're using POSIX 2008.09, which obviously includes POSIX 1993.09. Due to the lack of this code snippet, uClibc-ng <features.h> only enables: !defined _POSIX_SOURCE && !defined _POSIX_C_SOURCE) but not: So we need an _XOPEN_SOURCE level of at least 500 for POSIX 1993.09 definitions to be available. This is confirmed by the feature_test_macros man page, which states: _XOPEN_SOURCE < 500 _POSIX_C_SOURCE is defined with the value 2. 500 <= _XOPEN_SOURCE < 600 _POSIX_C_SOURCE is defined with the value 199506L. When this is fixed, another issue arises with older glibc toolchains (such as Sourcery ARM), where fd_set is no longer defined. Inded, with POSIX-1.2001 being enabled, we need to include <sys/select.h> to access the fd_set definition and friends (see man fd_set for details). This commit was tested with two glibc toolchains (recent and old), one uClibc-ng toolchain and one musl toolchain.

Subject: [PATCH] Use LONG_BIT to define RADIX_BITS
This allows to avoid having to support each CPU architecture
individually.

Also, add the necessary defines in the makefile to expose
LONG_BIT. Adding those defines end up requiring using <sys/select.h>
as we're now using >= POSIX.1-2001 definitions of fd_set and friends.
