[Buildroot] [PATCH 1/1] berkeleydb: fix build on powerpc64le

[Sam Bobroff]

Fixes

The issue appears as a link failure in exim, where pthread symbols are
undefined (they are not even used by the binary that causes the first
failure). This is caused by libdb (used by exim) producing static
rather than shared libraries, and this is due to berkeleydb's
configure failing to correctly detect shared library support.

Add a case for powerpc64le to allow correct detection of shared library
support in the linker.

+Currently, dist/configure on powerpc64le fails to determine the
+availability of shared library support in the toolchain, causing
+static libraries to be built even when shared libraries are supported.
+This can lead to linker failures in packages that use libdb.
+
+Add a case for powerpc64le which corrects the problem.
