package/libxslt: fix bfin compile
Fixes: http://autobuild.buildroot.org/results/df4/df4bf247c92847024dff88ce58a5f47343f06258/ http://autobuild.buildroot.org/results/b33/b33f34dc23f7429928d7d0b1478e71d8e7fffed2/ http://autobuild.buildroot.org/results/cad/cad02570ec039511b9495e82d98439e9f0724b37/ And many more. A GCC bug is triggered when the compiler is run with an optimization level '-Os/-O2/-O3' for the Blackfin architecture: ``` error: unable to find a register to spill in class 'CCREGS' ``` Workaround this bug by forcing an optimization level of '-O1' when building libxslt for the Blackfin architecture.
