gnu: gdb: Fix build of target-specific versions.

Since recently there has been a change to gdb package that introduced
configure-flags, three gdb packages broke, since they assumed there are no
configure-flags in gdb.  That means they produced the same gdb as gdb-14.

This patche fixes that by ensuring configure-flags are appended to original package.

* gnu/packages/embedded.scm (make-gdb-arm-none-eabi)[arguments]: Append
configure-flags to original flags.
* gnu/packages/gdb.scm (gdb-multiarch)[arguments]: Likewise.
* gnu/packages/gdb.scm (avr-gdb)[arguments]: Likewise.
