[Buildroot] [PATCH] bash: fix static build

[Baruch Siach]

When building bash statically, configure does not initialize the
SHOBJ_STATUS variable. The SHOBJ_STATUS make variable in
examples/loadables/Makefile.in must resolve to either 'supported' or
'unsupported'. Otherwise, the install-$(SHOBJ_STATUS) target does not
exist.

This leads to the following build failure:

make[2]: Entering directory '.../output/build/bash-4.4/examples/loadables'
make[2]: *** No rule to make target 'install-', needed by 'install'.  Stop.
make[2]: Leaving directory '.../output/build/bash-4.4/examples/loadables'
Makefile:793: recipe for target 'install' failed

with the following defconfig:

BR2_arm=y
BR2_STATIC_LIBS=y
BR2_PACKAGE_BUSYBOX_SHOW_OTHERS=y
BR2_PACKAGE_BASH=y

Set SHOBJ_STATUS in the configure environment as a workaround.

For some reason the autobuilders never caught this issue since the 4.4
version bump last November (commit cde22e1fd340).
