FreeBSD does not have the <asm/hwcap> header, requiring some slightly different code to check for NEON availability. This code might also apply to other BSD-like operating systems such as NetBSD, OpenBSD, DragonflyBSD, or iOS, but I haven't checked.

Tesseract requires the <asm/hwcap.h> header to detect the availability
of NEON instructions on armv7.  This commit adds a patch to use the
appropriate FreeBSD interface for this purpose.  This issue has already
been reported to up stream.

While this pull request was an important fix for ARM hosts, we had a similar severe problem for amd64 / x86_64 host. See issue #3964.
