libostree build fails when introspection is enabled:
./.libs/libostree-1.so: error adding symbols: File in wrong format
collect2: error: ld returned 1 exit status
src/libostree/ostree-repo-deprecated.h:28: Warning: OSTree: symbol='G_GNUC_DEPRECATED_FOR': Skipping foreign symbol from namespace Gio
linking of temporary binary failed: Command '['/bin/bash', './libtool', '--mode=link', '--tag=CC', '--silent', 'gcc', [...] ]' returned non-zero exit status 1.
This is because the build system fir libiostree hard-codes CC=gcc when
calling the GOI scanner, which obviously causes build failures when in
cross-compilation.
In d264351cfcca (package/libostree: disable introspection), we just
papered over the problem by forcibly disabling introspection altogether.
Turns out the fix is realatively simple: we can just override the
INTROSPECTION_SCANNER_ENV variable when calling make, which will revert
to the behaviour we expect: to use the cross-compiler in the GOI scanner
wrapper.
Thanks to Adam for pointing out at INTROSPECTION_SCANNER_ENV in the
first place. :-)
