e838a9847580527b8321d65e57b1c53cc2af6bf4 depends: re-enable using -flto when building expat (fanquake) 304452558c7f6f5e32ba13d8f05325790c8a4f5f depends: expat 2.4.8 (fanquake) Pull request description: Currently, when building the expat package in depends, using `-flto` (`LTO=1`), the configure check can fail, because it cannot determine the system endianess: ```bash configure:18718: result: unknown configure:18733: error: unknown endianness presetting ac_cv_c_bigendian=no (or yes) will help ``` Fix that by defining `_DEFAULT_SOURCE`, which in turn defines `__USE_MISC` (`features.h`): ```c #if defined _DEFAULT_SOURCE # define __USE_MISC1 #endif ``` which exposes additional definitions in `endian.h`: ```c #include <features.h> /* Get the definitions of __*_ENDIAN, __BYTE_ORDER, and __FLOAT_WORD_ORDER. */ #include <bits/endian.h> #ifdef __USE_MISC # define LITTLE_ENDIAN__LITTLE_ENDIAN # define BIG_ENDIAN__BIG_ENDIAN # define PDP_ENDIAN__PDP_ENDIAN # define BYTE_ORDER__BYTE_ORDER #endif ``` and gives us a working configure. You could test building this change with Guix + LTO with [this branch](https://github.com/fanquake/bitcoin/tree/lto_in_guix). Note that that build may fail for other reasons (on x86_64), unrelated to this change.
