[Buildroot] [PATCH 1/2] mtd: fix build failure with blackfin external toolchain

[Rahul Bedarkar]

With blackfin uClibc toolchain, we see following build errors

integck.c: In function 'parse_mount_options':
integck.c:2889: error: 'MS_DIRSYNC' undeclared (first use in this function)
integck.c:2889: error: (Each undeclared identifier is reported only once
integck.c:2889: error: for each function it appears in.)
integck.c:2899: error: 'MS_RELATIME' undeclared (first use in this function)
<builtin>: recipe for target 'integck' failed
make[2]: *** [integck] Error 1

header <sys/mount.h> from this toolchain is missing definitions for
MS_DIRSYNC and MS_RELATIME mount flags. But those are available from
header <linux/fs.h>. Even tests/fs-tests/lib/tests.c uses these flags
and includes both <sys/mount.h> and <linux/fs.h> headers.

This patch fixes above build error by including header <linux/fs.h>

Fixes:
