objtool: Use HOSTCFLAGS for HAVE_XXHASH test
Previously, HAVE_XXHASH is tested by invoking HOSTCC without HOSTCFLAGS.
Consider the following scenario:
- The host machine has libxxhash installed
- We build the kernel with HOSTCFLAGS containing a --sysroot that does
not have xxhash.h (for hermetic builds)
In this case, HAVE_XXHASH is set to y, but when it builds objtool with
HOSTCFLAGS, because the --sysroot does not contain xxhash.h, the
following error is raised:
<...>/common/tools/objtool/include/objtool/checksum_types.h:12:10: fatal error: 'xxhash.h' file not found
12 | #include <xxhash.h>
| ^~~~~~~~~~
To resolve the error, we test HAVE_XXHASH by invoking HOSTCC with
HOSTCFLAGS.
