Compiling hardfloat binaries on Synology Diskstation

[gbaderg]

Package: gcc

For existing package: gcc
Trying to compile "sox" using export CFLAGS="-O2 -pipe -march=armv7-a -mtune=cortex-a9 -fno-caller-saves -mfloat-abi=hard "

• expected behavior: can compile with support for HF hardfloat processing using -mfloat-abi=hard
• actual behavior: using "hard" throws error message during configure. "soft" and "softfp" for -mfloat-abi run successfully.
  configure: error: C compiler cannot create executables ---> See `config.log' for more details:

configure:3703: gcc -O2 -pipe -march=armv7-a -mtune=cortex-a9 -fno-caller-saves -mfloat-abi=hard   -Wl,-rpath=/opt/lib -

Entware is built with softfloat option to be compatible with broadcom arm routers. You need to rebuild and reinstall ALL entware without this option.
