Provide instructions on creating curl_config.h

# Google Android makefile for curl and libcurl

#

# Place the curl source (including this makefile) into external/curl/ in the

# Android source tree.  Then build them with 'make curl' or just 'make libcurl'

# from the Android root.

# from the Android root. Tested with Android 1.5

#

# Note: you must first create a curl_config.h file by running configure in the

# Android environment. I haven't found an easy way to do this yet. If there is

# no easy way, a static config-android.h may need to be created and checked in

# to the libcurl source tree.

# Android environment. The only way I've found to do this is tricky. Perform a

# normal Android build with libcurl in the source tree, providing the target

# "showcommands" to make. The build will eventually fail (because curl_config.h

# doesn't exist yet), but the compiler commands used to build curl will be

# shown. Now, from the external/curl/ directory, run curl's normal configure

# command with flags that match what Android itself uses. This will mean

# putting the compiler directory into the PATH, putting the -I, -isystem and

# -D options into CPPFLAGS, putting the -m, -f, -O and -nostdlib options into

# CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the path

# to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o. Remember

# that the paths must be absolute since you will not be running configure from

# the same directory as the Android make.  The normal cross-compiler options

# must also be set.

#

# The end result will be a configure command that looks something like this

# (the environment variable A is set to the Android root path):

#

#  A=`realpath ../..` && \

#  PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \

#  ./configure --host=arm-linux CC=arm-eabi-gcc \

#  CPPFLAGS="-I $A/system/core/include ..." \

#  CFLAGS="-fno-exceptions -Wno-multichar ..." \

#  LIB="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\

#  /interwork/libgcc.a ..." \
