[PATCH] Attempt to fix build of sra-tools on i686.

[Ricardo Wurmus]

Currently sra-tools fails to build on i686 because the custom
configuration system cannot find the "ilib" directory for "ncbi-vdb".
Turns out that "ncbi-vdb" had a broken "install-interfaces" phase on
i686.

The attached patch fixes the phase on i686 and should thus fix the build
of sra-tools on i686.

Subject: [PATCH] gnu: ncbi-vdb: Use "i386" instead of "i686" in directory
 name.

* gnu/packages/bioinformatics.scm (ncbi-vdb)[arguments]: Copy libraries from
  "linux/gcc/i386" directory instead of "linux/gcc/i686" when building on
  i686.
