[Buildroot] [PATCH 1/2] lmbench: mark scripts/build as bash script

[Markus Mayer <mmayer@broadcom.com>]

While bash supports the "+=" operator for environment variables,
/bin/sh does not. scripts/build is making use of "+=" but declares
itself to be a /bin/sh script. This leads to errors of the form
    ../scripts/build: 21: ../scripts/build: LDLIBS+= -lm: not found
and doesn't change the contents of LDLIBS as was the intention.

Therefore, we change the interpreter to /bin/bash, which makes things
work as intended.
