[Samuel Casa]

here some additional configure / gcc configurations i have tested:

ok -> does work!
| Compiler full flags................................... :
-I$(top_srcdir)/config -I$(top_srcdir) -I$(top_srcdir)
-I$(top_srcdir)/include -D_REENTRANT -D_POSIX_PTHREAD_SEMANTICS -Wall
-O0 -mcpu=cortex-a8 -mfloat-abi=hard -mfpu=vfpv3 -mthumb
-mno-thumb-interwork -mhard-float

ok -> but i dont want thumb!
