Subject: [PATCH] build: Fix cross-compilation.
|
|
|
|
The cross-compilation issues corrected by this change were discovered
|
|
when attempting to cross-compile disarchive for the i586-gnu target on
|
|
GNU Guix.
|
|
|
|
* configure.ac [O_NOFOLLOW]: Rewrite test using AC_COMPUTE_INT, which
|
|
is supported even when cross-compiling.
|
|
(GUILD_TARGET_OPTION): New computed variable.
|
|
* build-aux/guile.am ($(AM_V_GUILEC)GUILE_AUTO_COMPILE): Use it.
