[Buildroot] [PATCH v2 1/1] package/exfat-utils: fix compilation error with musl

[Brendan Heading]

exfat-utils build would not build on Linux unless __GLIBC__ was defined.
Patch added to use more relaxed __linux__ instead.

See http://autobuild.buildroot.net/results/c60/c60d0f9a93c90d41c3c86c78b0a0

+[PATCH] fix compilation when libc does not define __GLIBC__
+
+libexfat would only compile on Linux with __GLIBC__ defined. Changed
+to use __linux__ which likely better fits the original intent.
