[Buildroot] [PATCH 1/1] package/openfpgaloader: needs gcc >= 4.9

[Fabrice Fontaine]

openfpgaloader needs C++11 as specified in CMakeLists.txt:
set(CMAKE_CXX_STANDARD 11)

The build on gcc 4.8 fails on:

/home/buildroot/autobuild/instance-1/output-1/build/openfpgaloader-849e5751e06d4d00f323205d5f02ee01f9f59a61/src/spiFlash.cpp: In member function 'void SPIFlash::jtag_write_read(uint8_t, uint8_t*, uint8_t*, uint16_t)':
/home/buildroot/autobuild/instance-1/output-1/build/openfpgaloader-849e5751e06d4d00f323205d5f02ee01f9f59a61/src/spiFlash.cpp:92:43: error: variable-sized object 'jtx' may not be initialized
  uint8_t jtx[xfer_len] = {reverseByte(cmd)};
                                           ^
