Subject: powertop: Fix build for !uclibc

* EXTRA_LDFLAGS isn't defined for !uclibc and configure fails when it reads it unexpanded, see config.log snippet:

   configure:4177: checking whether the C compiler works
   configure:4199: i586-oe-linux-gcc  -m32 -march=i586 --sysroot=/OE/sysroots/qemux86  -O2 -pipe -g -feliminate-unused-debug-types  -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed ${EXTRA_LDFLAGS} conftest.c  >&5
   i586-oe-linux-gcc: error: ${EXTRA_LDFLAGS}: No such file or directory
   configure:4203: $? = 1
   configure:4241: result: no

Hi Saul,

as I said, attached patch was taken/ported from OE-Core Dizzy, commit c8f9b5c9a8e5179c2013f25decd6a5483df9c716.

Please apply it to OE-Core _Daisy_ branch, which is affected, too.

Is there anything else I should do, any additional information I need to provide, anything I did wrong? Kindly respond.

Thanks & best regards,
Jens
