[Buildroot] [git commit branch/2019.02.x] package/lmbench: mark scripts/build as bash script

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ededb6cf77eef64df3ffa919cdd463a81f7a1e3f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

scripts/build makes use of the "+=" operator which is not supported by
a pure POSIX shell. We switch to /bin/bash in order to avoid errors of
the form:

    ../scripts/build: 21: ../scripts/build: LDLIBS+= -lm: not found
